Understanding Second Law of Thermodynamics !
The ‘Second Law of Thermodynamics’ is a fundamental law of nature, unarguably one of the most valuable discoveries of mankind; however this law is slightly confusing for most engineers or students. The main reason for this is because it has so many complex terms in it and that there are many ways that this second law can be stated, but most importantly, the majority do not understand what are the applications of this law. In this video we will create a real physical insight into this law with a minimum use of mathematics.

Second Law of Thermodynamics - Heat Energy, Entropy & Spontaneous Processes
This physics video tutorial provides a basic introduction into the second law of thermodynamics. It explains why heat flows from a hot object to a cold object. The second law of thermodynamics states that the change in entropy of a natural process is always a positive. For an ideal reversible process, the entropy change is equal to or greater than zero.

SECOND LAW OF THERMODYNAMICS | Easy & Basic
Hello there! It’s Easy Engineering once again! And today’s topic is the SECOND LAW OF THERMODYNAMICS.
This topic has made most of the engineering students confused so for this discussion we will make it as easier as possible.
So the Major statements for the second law are the following:
Clausius Statement;
It is impossible for any system to operate in such a way that the sole result would be an energy transfer by heat from a cooler to a hotter body
Kelvin-Plank Statement;
It is impossible for any system to operate in a thermodynamic cycle and deliver a net amount of energy by work to its surroundings while receiving energy by heat transfer from a single reservoir
Entropy Statement;
It is impossible for any system to operate in a way that entropy is destroyed
So to make it easy we m...

What is the Second Law of Thermodynamics?
What is entropy? Why is it always increasing? And what does that even mean? Dr Valeska Ting explains the second law of thermodynamics.
This is the day 12 of our 2016 advent calendar on thermodynamics. Watch all the films here: http://www.rigb.org/christmas-lectures/supercharged-fuelling-the-future/thermodynamics-2016-advent-calendar?utm_source=youtube&utm_medium=social&utm_campaign=201612_channel_advent
Valeska walks us from a simple mathematical demonstration, through coffee and refrigerators, and right up to the end of the Universe and everything in it.
The second law of thermodynamics states that entropy, which is often thought of as simple ‘disorder’, will always increase within a closed system. Ultimately, this is one of the key elements dictating an arrow of time in the Universe....

What is the 2nd law of thermodynamics?
Useful for describing a variety of processes in chemical engineering to computer design, the second law of thermodynamics is as fundamental as it is hard to grasp.
This law has its roots so deep in every aspect of the universe that, once you understand this core concept, you will know the reason why your coffee gets cold and why some scientists think that our universe will end in heat-death at the same time.
However, before going into detail about the second law, let’s start with a general introduction as a warm-up by answering the following questions: “What are the laws of thermodynamics, and what is the first law of thermodynamics?”
There are three laws of thermodynamics. The first law states that it is impossible to create or destroy energy, it just transitions from one form to ano...

Hello there! It’s Easy Engineering once again! And today’s topic is the SECOND LAW OF THERMODYNAMICS.
This topic has made most of the engineering students confused so for this discussion we will make it as easier as possible.
So the Major statements for the second law are the following:
Clausius Statement;
It is impossible for any system to operate in such a way that the sole result would be an energy transfer by heat from a cooler to a hotter body
Kelvin-Plank Statement;
It is impossible for any system to operate in a thermodynamic cycle and deliver a net amount of energy by work to its surroundings while receiving energy by heat transfer from a single reservoir
Entropy Statement;
It is impossible for any system to operate in a way that entropy is destroyed
So to make it easy we made 2 easier statements that would help us more in understanding this law.
So First is, well let’s call this as “High to Low”
For any process, a natural flow will always be from higher energy value to lower energy value
For example COFFEE, the temperature of the coffee is higher than its cup and as it says (from higher energy value) so the temperature of coffee gets transferred to the cup which is cooler (lower energy value) and that’s why the cup gets hotter.
Or try A compressed gas in a balloon, if you open a small hole in a balloon, does the outside air enters the balloon? No, instead the gas in the balloon goes outside transfers its pressure to the outside air. Because the gas in the balloon has higher pressure than the outside air.
A tank full of water is connected to an empty tank with a valve in the middle. Now open the valve and what happens? The full tank level is lowered transferring its level to the empty tank.
How about the topics being discussed in your classroom? The transfer of ideas comes from the professor which has more ideas to its students who has lower ideas.
Or even think of the salary from employer to employee. True right?
So let’s move to the second one, let’s call this “Perfect is impossible”
For every real-world process, there will always be losses.
That means You cannot convert all of your car’s fuel into mechanical energy which can rotate your car’s wheels, proof? It’s the gases you see on the car’s muffler
Or try bouncing a ball by first throwing it up to the air, see that as the number of bounces increases the level of bounce decreases because of the loss of energy which is transferred to the ground
How about our foods? That is our source of energy. We can see the losses through our sweat, urine, and solid waste.
So that’s it! I hope we made it easier for you!
Before this video ends we would like to make a note that the Second Law of Thermodynamics is a Law and it is applicable to everything in our world. I hope this changes your perspective on this law. And if you have comments or you want to correct us please comment below, we would love to listen.

What is entropy? Why is it always increasing? And what does that even mean? Dr Valeska Ting explains the second law of thermodynamics.
This is the day 12 of our 2016 advent calendar on thermodynamics. Watch all the films here: http://www.rigb.org/christmas-lectures/supercharged-fuelling-the-future/thermodynamics-2016-advent-calendar?utm_source=youtube&utm_medium=social&utm_campaign=201612_channel_advent
Valeska walks us from a simple mathematical demonstration, through coffee and refrigerators, and right up to the end of the Universe and everything in it.
The second law of thermodynamics states that entropy, which is often thought of as simple ‘disorder’, will always increase within a closed system. Ultimately, this is one of the key elements dictating an arrow of time in the Universe. And how is it possible that complex ordered organisms and structures have developed, if everything should be becoming less ordered over time? Valeska explains.
The 2016 advent calendar explores the four laws of thermodynamics with a new short film each day, with explosive demonstrations, unique animations, and even a musical number.

The second law of thermodynamics says that entropy will inevitably increase. Eventually, it will make life in the universe impossible. What does this mean? And is it correct? In this video, I sort out what we know about the arrow of time and why I don't believe that entropy will kill the universe.

Useful for describing a variety of processes in chemical engineering to computer design, the second law of thermodynamics is as fundamental as it is hard to grasp.
This law has its roots so deep in every aspect of the universe that, once you understand this core concept, you will know the reason why your coffee gets cold and why some scientists think that our universe will end in heat-death at the same time.
However, before going into detail about the second law, let’s start with a general introduction as a warm-up by answering the following questions: “What are the laws of thermodynamics, and what is the first law of thermodynamics?”
There are three laws of thermodynamics. The first law states that it is impossible to create or destroy energy, it just transitions from one form to another. The second law explains the direction of energy transfer with three major statements. These statements are Clausius, Kelvin-Planck, and Entropy.
These statements can be summarized as the natural flow always flowing from higher energy to lower energy and there will always be losses in the process.
To exemplify the first one, imagine the coffee you might have poured into your mug this morning. The heat or the thermal energy moved from hot coffee, high in energy, to your mug which has lower energy in the absence of heat. For the second one, you can think of bouncing a ball by throwing it into the air, the ball eventually stops bouncing due to energy loss transferred into the ground.
If you want to learn more about convection, heat energy and want an answer to the question of “What is the second law of thermodynamics?“, be sure to check our video!
