Welcome to Tutway, a unique platform where learning is fun !
Now there is no distinction between kids' fun time and study time. Say goodbye to the days of cramming those dull and ponderous books, which made learning a tedious task. We believe in the straightforward idea that audio-visual learning is the most effective tool for learning. Many researchers have proven that kids learn a lot by playing interactive games and watching audio-visual animated lessons compared to reading from books. To understand the new concepts, Kids show more interest in adopting unique ways of learning. We have brought a programme that covers the crucial ideas and ...

Properties of Water | Hydrogen Bonding in Water | Biology | Biochemistry
Why is water essential for Life to exist on Earth? We are about 60% water - and there are some organisms that are as much as 90% water! What is so important about water? How does it support life?
In this video, we discuss the special properties of water that make it the “Solvent of Life.” Chief among these properties is the extensive Hydrogen Bonding between water molecules that make water an extremely cohesive liquid (the molecules stick together). Due to the extensive hydrogen bonding, water has some emergent properties that impact life on Earth in many ways. These include:
Cohesion
Adhesion
High surface tension
High specific heat
High heat of vaporization
Ice Floats (Ice is less dense as a solid than liquid water)
For each of these properties, we discuss how they impact living c...

Properties of Water
This video examines water's structure and polarity, its tendency to form hydrogen bonds, and the high specific heat, cohesion, adhesion, surface tension and capillary action that all result from these hydrogen bonds. Water is such a common molecule that we often don’t think about it, but it has many properties that make it crucial for many biological processes.
Water Structure:
The water molecule is shaped like the letter V, with an oxygen in the center and two hydrogens joined to it by single covalent bonds. Both atoms contribute electrons to the covalent bonds, but the distribution is not equal. Overall the electrons spend more time close to oxygen than they do to hydrogen. This is because oxygen has a higher tendency to attract electrons, a property that we call “electronegativity” .

This structure makes water a very polar molecule. Without going into the beautiful details, Oxygen has a net negative charge while the opposite ends with the hydrogens have a net ...

A Level Biology Revision "Properties and Roles of Water Part 1"
You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/a-level-revision-videos/a-level-biology/
In this video, we start looking at the importance of water in Biology. First we explore the structure of the water molecule and see how water molecules are attracted to each other by forces called hydrogen bonds. We then look at the roles of water in Biology. These include as a habitat (both liquid water and ice) and how water can be used to cool organisms.

This video examines water's structure and polarity, its tendency to form hydrogen bonds, and the high specific heat, cohesion, adhesion, surface tension and capillary action that all result from these hydrogen bonds. Water is such a common molecule that we often don’t think about it, but it has many properties that make it crucial for many biological processes.
Water Structure:
The water molecule is shaped like the letter V, with an oxygen in the center and two hydrogens joined to it by single covalent bonds. Both atoms contribute electrons to the covalent bonds, but the distribution is not equal. Overall the electrons spend more time close to oxygen than they do to hydrogen. This is because oxygen has a higher tendency to attract electrons, a property that we call “electronegativity” .
Water Polarity:
Why is water polar? Since electrons have a negative charge and they spend a larger part of their time near oxygen, it gives the oxygen a partial negative charge, and the hydrogens a partial positive charge. When a molecule has more positive and more negative regions, we say it is “polar”.
Hydrogen Bonds:
Why does water form hydrogen bonds? Oppositely charged parts of water molecules are attracted to one another (negative oxygen and positive hydrogen) in what we call hydrogen bonds. It’s very important to remember that water REALLY likes to form hydrogen bonds. One water molecule can form up to four at a time. In liquid water, the hydrogen bonds are weak and last just a fraction of a second before they reform in another configuration. This constant breaking, rearranging and reforming of hydrogen bonds causes many of water’s unique properties, including its heat capacity, cohesion, adhesion, surface tension and capillary action.
Specific Heat Capacity:
Why does water have high specific heat capacity? Thanks to its hydrogen bonds, water can absorb a very large amount of heat energy without changing into a gas. Water has a high specific heat capacity, which means it needs a lot of heat in order to raise the temperature of 1 gram of water by 1 degree celsius. In short, because water really loves to form hydrogen bonds, it takes a LOT of heat energy to overcome this tendency, break the bonds and make water warm up.
Cohesion:
Water has a tendency to stick to itself because it easily forms these hydrogen bonds. At any point, a large percentage of water molecules hydrogen bonding with several neighbors. We call this tendency of water to stick to itself “cohesion”.
Surface Tension:
Usually, each water molecule is bonded to four other water molecules most of the time, and the force is the same in all directions. However, at the surface of the water, the outer molecules have fewer adjacent water molecules to bond to. So, instead they reinforce the bonds with the molecules next to them. Because there are forces pulling the outermost molecules down and to the side, but not up, it creates a stronger layer on the surface, and a net force that pulls molecules inwards. Because water really loves to form hydrogen bonds, the top layer is reinforced, creating surface tension.
Adhesion:
Water also has a tendency to stick to other polar objects. We call this behavior “adhesion”. Because water really loves to form hydrogen bonds, the water adheres weakly to a waxy surface, but strongly to itself, forming a rounded water bead instead of a puddle.
Capillary Action:
The combination of cohesion, adhesion and surface tension creates capillary action. This is when a liquid flows through a narrow space without any external forces like gravity. In capillary action, adhesion to the walls of a vessel is stronger than the cohesion between the water molecules. The liquid sticks to the walls then pulls other molecules up behind it, then climb higher, like a rock climber. If the diameter of the tube is too big, the molecules cannot climb the walls. Instead, they go as high as they can before gravity overpowers the adhesive and cohesive forces and stops the liquid moving up. This results in a “dip” called a “meniscus”.

Now, on to water aka dihydrogen monoxide aka H2O. Water is made up of one oxygen atom, and two hydrogen atoms. And looks something like this.
This structure makes water a very polar molecule. Without going into the beautiful details, Oxygen has a net negative charge while the opposite ends with the hydrogens have a net positive charge. This allows water molecules to form hydrogen bonds and gives water many of its other properties.
Cohesion and Adhesion are two such properties.
Cohesion is water’s attraction to itself. The hydrogen bonds that I mentioned facilitate this. This is also why water has surface tension, allowing bugs to walk on it. Additionally, cohesion keeps water a liquid at moderate temperatures instead of a gas.
Adhesion is water’s attraction to other surfaces. Water will adhere to anything it can form a hydrogen bonds with. This is the reason for capillary action, where water climbs up a narrow glass tube.
Another property of water is it’s high heat capacity.
Heat capacity is a substance ability to absorb heat. More accurately, it’s the amount of energy needed to raise one gram of a substance by one degree celsius. This allows water to absorb temperature changes and keep air temperature at moderate levels. Which is pretty cool…
Finally, water is known as the universal solvent, meaning that a wide range of substances can be dissolved in it. This includes hydrophilic and polar molecules like sugars and salts. Substances that generally don’t dissolve in water are hydrophobic, like oils.
So now you know a little more about the properties of H2O, and bare in mind, we only covered a portion of water’s amazing properties, so be sure to check the links in the description to learn more.

You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/a-level-revision-videos/a-level-biology/
In this video, we start looking at the importance of water in Biology. First we explore the structure of the water molecule and see how water molecules are attracted to each other by forces called hydrogen bonds. We then look at the roles of water in Biology. These include as a habitat (both liquid water and ice) and how water can be used to cool organisms.
