Thermal conduction
Thermal conduction is the transfer of heat (internal energy) by microscopic collisions of particles and movement of electrons within a body. The microscopically colliding objects, that include molecules, atoms, and electrons, transfer disorganized microscopic kinetic and potential energy, jointly known as internal energy. Conduction takes place in all phases of matter, such as solids, liquids, gases and plasmas. The rate at which energy is conducted as heat between two bodies is a function of the temperature difference (temperature gradient) between the two bodies and the properties of the conductive medium through which the heat is transferred. Thermal conduction was originally called diffusion.
Heat spontaneously flows from a hotter to a colder body. For example, heat is conducted from the hotplate of an electric stove to the bottom of a saucepan in contact with it. In the absence of external drivers, within a body or between bodies, temperature differences decay over time, and thermal equilibrium is approached, temperature becoming more uniform.

Conduction -Convection- Radiation-Heat Transfer
Heat is the transfer of energy from objects of different temperatures. As objects warm-up or cool down their kinetic energy changes. Kinetic energy is the energy of motion. In this video, I focus on three ways heat can be transferred, Conduction, Convection, and Radiation. Conduction involves direct contact between objects and usually occurs among solids. Convection is caused by unequal heating and the density of the different objects causes movement of fluid away from the heat source. Radiation occurs without objects touching and occurs in space. For example, the energy of the sun warms objects on Earth due to radiation. I show several examples or demonstrations for each type of heat transfer.

What Is Thermal Energy?
All matter is made up of tiny particles. Whether matter is in a solid, liquid or gas, these particles are always in motion. How much these particles move is called thermal energy.
The more thermal energy matter has, the higher its temperature. Temperature is how hot or cold matter is. It is a measure of the average kinetic energy of the particles in matter. The faster the particles mover, the greater the temperature.
When matter gains thermal energy, the particles that make up the matter move faster. Its thermal energy increases and its temperature also increases. When matter loses thermal energy, the particles that make up the matter move slower. Its thermal energy decreases and its temperature decreases.
So how does matter gain thermal energy? The movement of thermal energy is called heat. Heat occurs whenever there is difference in temperature.
Let’s look at an example of the heat that occurs when a hot object comes in contact with a cold object. In both objects, the particles are moving – they have kinetic energy. When the objects are touching, their particles collide with each other. As they collide, the hot object passes energy to the cold object. The hot object gets cooler and the cold object gets warmer. Heat will continue to move in this way until the temperature of both objects is equal.
When you place a cold metal spoon into a hot cup of tea, energy moves from the hot tea to the spoon. The tea loses thermal energy and gets cooler. The spoon gains thermal energy and gets hotter. The metal spoon will continue to gain thermal energy from the hot tea until the temperature of the tea and the spoon are equal.
Just as heat moves from hot to cold between objects, it also moves in this way within objects. Let’s look at an example of placing a metal rod over a fire. The heat from the fire will cause the particles at the tip of the rod to gain thermal energy and its temperature increases. These particles then collide with the particles adjacent to them. In this way, heat in transferred from the hot region to the cold region of the metal rod.
Thermal energy moves in three main ways – conduction, convection and radiation.
Think again how heat moved in the metal rod placed on a fire. The thermal energy moved from the hot part of the rod to the cooler part of the rod. This movement of heat within an object is called conduction. Conduction also occurs when objects are touching. If you were to hold the cool end of the rod, before too long it would feel warm as thermal energy moves by conduction to your hand.
Heat transfer from a hot cup to your hands and cooking a piece of fish in a pan are also examples of conduction.
Liquids and gases are similar in that they have no fixed shape. They are fluids. Thermal energy can be transferred from one region of a fluid to another due to movements within the fluid. This movement of thermal energy, called convection, is caused by hot parts of the fluid rising and the cooler parts of the fluid sinking.
Think about the water in a kettle as it is heated. The water touching the heating element is heated by conduction. The water becomes warm and rises. As it does so, the cooler water sinks and a current is created within the water. The current causes the thermal energy to spread through the water in the kettle.
The heating of air in a hot air balloon is also an example of convection.
For thermal energy to move by conduction and convection it must travel through matter. Between the Sun and the Earth is empty space. How does the heat from the Sun warm the Earth and other planets in the solar system? The answer is radiation. Radiation is the transfer of energy through electromagnetic waves.
The warmth you feel when you place your hand near an electric heater or a campfire are examples of heat in the form of radiation.

Observe how three spoons of different materials are different in their heat conductivity.
Thermal Conductivity
When an object is heated, thermal energy moves from hot to cold. This occurs as the particles within the object collide. In order for heat to move from one region to another, it must pass through all of the particles in between. The time it takes for this to occur is different in different materials and different states of matter. The ability of a material or matter to transfer thermal energy is called thermal conductivity.
Some materials allow heat to pass through them more easily than others. Materials that allow heat to pass through them easily are called good conductors of heat. The metal used to make the pot is a good conductor of heat. It allows heat to flow easily from the hotplate to the food.
Materials that do not allow heat to pass through them easily are called poor conductors of heat, or heat insulators. The plastic handle on the pot is a poor conductor of heat. Heat cannot flow through the plastic easily, so it does not get as hot as the metal.
Wool and fabrics such as fleece are good heat insulators. They are often used to produce clothing to keep people warm.
Generally, matter in a solid state are better conductors of heat than matter in a liquid state. This is because the particles in solids are more tightly packed together than the particles in liquids. Similarly, liquids are generally better conductors of heat than gases.
The more thermal energy matter has, the higher its temperature. Temperature is how hot or cold matter is. It is a measure of the average kinetic energy of the particles in matter. The faster the particles mover, the greater the temperature.
When matter gains thermal energy, the particles that make up the matter move faster. Its thermal energy increases and its temperature also increases. When matter loses thermal energy, the particles that make up the matter move slower. Its thermal energy decreases and its temperature decreases.
So how does matter gain thermal energy? The movement of thermal energy is called heat. Heat occurs whenever there is difference in temperature.
Let’s look at an example of the heat that occurs when a hot object comes in contact with a cold object. In both objects, the particles are moving – they have kinetic energy. When the objects are touching, their particles collide with each other. As they collide, the hot object passes energy to the cold object. The hot object gets cooler and the cold object gets warmer. Heat will continue to move in this way until the temperature of both objects is equal.
When you place a cold metal spoon into a hot cup of tea, energy moves from the hot tea to the spoon. The tea loses thermal energy and gets cooler. The spoon gains thermal energy and gets hotter. The metal spoon will continue to gain thermal energy from the hot tea until the temperature of the tea and the spoon are equal.
Just as heat moves from hot to cold between objects, it also moves in this way within objects. Let’s look at an example of placing a metal rod over a fire. The heat from the fire will cause the particles at the tip of the rod to gain thermal energy and its temperature increases. These particles then collide with the particles adjacent to them. In this way, heat in transferred from the hot region to the cold region of the metal rod.
Temperature vs Thermal Energy
Temperature is a measure of the average kinetic energy of the particles in a given object. It is different from thermal energy – which is a measure of the total kinetic energy of an object’s particles.
Consider a nail that has been heated until it glows white-hot. Its temperature is around 1,000ºC. The particles inside the nail are moving back and forth with high kinetic energy.
Now consider a large steel beam that supports a bridge. On a winter morning, the temperature of the bridge is just 5ºC – much colder than the metal nail. However the metal beam contains more thermal energy than the nail as it contains far more particles.
Similarly, a boiling pot of water has less kinetic energy than the water under an ice-covered lake.
Transfer of Thermal Energy – Conduction
Thermal energy moves in three main ways – conduction, convection and radiation.
Think again how heat moved in the metal rod placed on a fire. The thermal energy moved from the hot part of the rod to the cooler part of the rod. This movement of heat within an object is called conduction. Conduction also occurs when objects are touching. If you were to hold the cool end of the rod, before too long it would feel warm as thermal energy moves by conduction to your hand.
Heat transfer from a hot cup to your hands and cooking a piece of fish in a pan are also examples of conduction.

What Is Thermal Energy?
All matter is made up of tiny particles. Whether matter is in a solid, liquid or gas, these particles are always in motion. How much these particles move is called thermal energy.
The more thermal energy matter has, the higher its temperature. Temperature is how hot or cold matter is. It is a measure of the average kinetic energy of the particles in matter. The faster the particles mover, the greater the temperature.
When matter gains thermal energy, the particles that make up the matter move faster. Its thermal energy increases and its temperature also increases. When matter loses thermal energy, the particles that make up the matter move slower. Its thermal energy decreases and its temperature decreases.
So how does matter gain thermal energy? The movement of thermal energy is called heat. Heat occurs whenever there is difference in temperature.
Let’s look at an example of the heat that occurs when a hot object comes in contact with a cold object. In both objects, the particles are moving – they have kinetic energy. When the objects are touching, their particles collide with each other. As they collide, the hot object passes energy to the cold object. The hot object gets cooler and the cold object gets warmer. Heat will continue to move in this way until the temperature of both objects is equal.
When you place a cold metal spoon into a hot cup of tea, energy moves from the hot tea to the spoon. The tea loses thermal energy and gets cooler. The spoon gains thermal energy and gets hotter. The metal spoon will continue to gain thermal energy from the hot tea until the temperature of the tea and the spoon are equal.
Just as heat moves from hot to cold between objects, it also moves in this way within objects. Let’s look at an example of placing a metal rod over a fire. The heat from the fire will cause the particles at the tip of the rod to gain thermal energy and its temperature increases. These particles then collide with the particles adjacent to them. In this way, heat in transferred from the hot region to the cold region of the metal rod.
Thermal energy moves in three main ways – conduction, convection and radiation.
Think again how heat moved in the metal rod placed on a fire. The thermal energy moved from the hot part of the rod to the cooler part of the rod. This movement of heat within an object is called conduction. Conduction also occurs when objects are touching. If you were to hold the cool end of the rod, before too long it would feel warm as thermal energy moves by conduction to your hand.
Heat transfer from a hot cup to your hands and cooking a piece of fish in a pan are also examples of conduction.
Liquids and gases are similar in that they have no fixed shape. They are fluids. Thermal energy can be transferred from one region of a fluid to another due to movements within the fluid. This movement of thermal energy, called convection, is caused by hot parts of the fluid rising and the cooler parts of the fluid sinking.
Think about the water in a kettle as it is heated. The water touching the heating element is heated by conduction. The water becomes warm and rises. As it does so, the cooler water sinks and a current is created within the water. The current causes the thermal energy to spread through the water in the kettle.
The heating of air in a hot air balloon is also an example of convection.
For thermal energy to move by conduction and convection it must travel through matter. Between the Sun and the Earth is empty space. How does the heat from the Sun warm the Earth and other planets in the solar system? The answer is radiation. Radiation is the transfer of energy through electromagnetic waves.
The warmth you feel when you place your hand near an electric heater or a campfire are examples of heat in the form of radiation.

Continuing the heat transfer series, in this video we take a look at conduction and the heat equation.
Fourier's law is used to calculate the rate at which heat is transferred through an object due to conduction. But it can only be applied if the temperature distribution within the body is known. To determine the temperature distribution, the heat equation needs to be solved.

Heat is the transfer of energy from objects of different temperatures. As objects warm-up or cool down their kinetic energy changes. Kinetic energy is the energy of motion.
In this video, I focus on three ways heat can be transferred,
Conduction, Convection, and Radiation.
Conduction involves direct contact between objects and usually occurs among solids.
Convection is caused by unequal heating and the density of the different objects causes movement of fluid away from the heat source.
Radiation occurs without objects touching and occurs in space.
For example, the energy of the sun warms objects on Earth due to radiation.
I show several examples or demonstrations for each type of heat transfer.

Observe how three spoons of different materials are different in their heat conductivity.
Thermal Conductivity
When an object is heated, thermal energy moves from hot to cold. This occurs as the particles within the object collide. In order for heat to move from one region to another, it must pass through all of the particles in between. The time it takes for this to occur is different in different materials and different states of matter. The ability of a material or matter to transfer thermal energy is called thermal conductivity.
Some materials allow heat to pass through them more easily than others. Materials that allow heat to pass through them easily are called good conductors of heat. The metal used to make the pot is a good conductor of heat. It allows heat to flow easily from the hotplate to the food.
Materials that do not allow heat to pass through them easily are called poor conductors of heat, or heat insulators. The plastic handle on the pot is a poor conductor of heat. Heat cannot flow through the plastic easily, so it does not get as hot as the metal.
Wool and fabrics such as fleece are good heat insulators. They are often used to produce clothing to keep people warm.
Generally, matter in a solid state are better conductors of heat than matter in a liquid state. This is because the particles in solids are more tightly packed together than the particles in liquids. Similarly, liquids are generally better conductors of heat than gases.
The more thermal energy matter has, the higher its temperature. Temperature is how hot or cold matter is. It is a measure of the average kinetic energy of the particles in matter. The faster the particles mover, the greater the temperature.
When matter gains thermal energy, the particles that make up the matter move faster. Its thermal energy increases and its temperature also increases. When matter loses thermal energy, the particles that make up the matter move slower. Its thermal energy decreases and its temperature decreases.
So how does matter gain thermal energy? The movement of thermal energy is called heat. Heat occurs whenever there is difference in temperature.
Let’s look at an example of the heat that occurs when a hot object comes in contact with a cold object. In both objects, the particles are moving – they have kinetic energy. When the objects are touching, their particles collide with each other. As they collide, the hot object passes energy to the cold object. The hot object gets cooler and the cold object gets warmer. Heat will continue to move in this way until the temperature of both objects is equal.
When you place a cold metal spoon into a hot cup of tea, energy moves from the hot tea to the spoon. The tea loses thermal energy and gets cooler. The spoon gains thermal energy and gets hotter. The metal spoon will continue to gain thermal energy from the hot tea until the temperature of the tea and the spoon are equal.
Just as heat moves from hot to cold between objects, it also moves in this way within objects. Let’s look at an example of placing a metal rod over a fire. The heat from the fire will cause the particles at the tip of the rod to gain thermal energy and its temperature increases. These particles then collide with the particles adjacent to them. In this way, heat in transferred from the hot region to the cold region of the metal rod.
Temperature vs Thermal Energy
Temperature is a measure of the average kinetic energy of the particles in a given object. It is different from thermal energy – which is a measure of the total kinetic energy of an object’s particles.
Consider a nail that has been heated until it glows white-hot. Its temperature is around 1,000ºC. The particles inside the nail are moving back and forth with high kinetic energy.
Now consider a large steel beam that supports a bridge. On a winter morning, the temperature of the bridge is just 5ºC – much colder than the metal nail. However the metal beam contains more thermal energy than the nail as it contains far more particles.
Similarly, a boiling pot of water has less kinetic energy than the water under an ice-covered lake.
Transfer of Thermal Energy – Conduction
Thermal energy moves in three main ways – conduction, convection and radiation.
Think again how heat moved in the metal rod placed on a fire. The thermal energy moved from the hot part of the rod to the cooler part of the rod. This movement of heat within an object is called conduction. Conduction also occurs when objects are touching. If you were to hold the cool end of the rod, before too long it would feel warm as thermal energy moves by conduction to your hand.
Heat transfer from a hot cup to your hands and cooking a piece of fish in a pan are also examples of conduction.

Thermal conduction
Thermal conduction is the transfer of heat (internal energy) by microscopic collisions of particles and movement of electrons within a body. The microscopically colliding objects, that include molecules, atoms, and electrons, transfer disorganized microscopic kinetic and potential energy, jointly known as internal energy. Conduction takes place in all phases of matter, such as solids, liquids, gases and plasmas. The rate at which energy is conducted as heat between two bodies is a function of the temperature difference (temperature gradient) between the two bodies and the properties of the conductive medium through which the heat is transferred. Thermal conduction was originally called diffusion.
Heat spontaneously flows from a hotter to a colder body. For example, heat is conducted from the hotplate of an electric stove to the bottom of a saucepan in contact with it. In the absence of external drivers, within a body or between bodies, temperature differences decay over time, and thermal equilibrium is approached, temperature becoming more uniform.
