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.

Can heat flow from dry ice to ice because of the temperature difference between the cold and colder body? Can we run the Sterling engine by using ice as the source of heat and dry ice as the sink?

@cdmarshall7448 2 года назад

Heat is the difference between temperature, the change in internal energy isn't heat. LOT makes it perfectly clear Energy, Heat and Temperature although closely related are not the exact same thing. I'm hoping you learned this already in the last 5 years but your never know? >“Heat is defined as the form of energy that is transferred across a boundary by virtue of a temperature difference or temperature gradient. Implied in this definition is the very important fact that a body never contains heat, but that heat is identified as heat only as it crosses the boundary. Thus, heat is a transient phenomenon." -Thermodynamics, G. J. V. Wylen, John Wiley & Sons, 1960

You never said the entropy of the universe tends to a maximum. How can you forget that?

@sds3841 2 года назад

If u have an endothermic reaction (delta H is positive) like H2 + I2 --> 2HI can you say whether the entropy rises or decreases and whether the reaction could be spontaneous?

@MiKi-ki9fi Год назад

The more concentrated molecule the less entropy. So the equation that you gave has less entropy. And also the reaction is spontaneous because normaly elements binds without energy input. ( as i guess)

so when you open a door from an airconditioned room, is the cold leaves/moves out or is it the heat comes in?

@gomerpyle6113 5 лет назад

@touchme-sama9759 4 года назад

Heat from outdoor comes in

@samwweir111 3 года назад

Which is why we always want our doors closed during the summer so we don't let the room get warm again

@andrewmcmillan484 2 года назад

Another example would be how your cooling system works on a car, or the air conditioning system works on your car.

@alimumtazR Год назад

In this case cold bulk of air leaves the room through convection but here conduction is being discussed so yeah there's that... :)

@callejondorado 3 года назад

a) Isn't it similar to say that the system naturally tends to a go to a state of equilibrium?, but that is predictable which is the opposite of saying that entropy=unpredictability.

@ankitsethi626 3 года назад

I have the same doubt.. it is natural for a system to reach equilibrium which is in order rather than disorder

If the entropy of the universe is always increasing how did evolution defy the second law of entropy?

@adamhanzlik8650 2 года назад

Its important to realise that the law applies to isolated systems. Evolution did not defy the law, as it was only able to achieve what it did with the help of a constant source of energy in the form of our Sun. If you look at our Solar System as a whole, you will see how the 2nd law of thermodynamics applies.

@sunbeam9222 3 месяца назад

Entropy is not increasing. It only does from human perception

@goldenladle7251 Год назад

So in other words evolution violates the law of entropy. Same with space, it is impossible to have a pressurized system adjacent to a vacuum.

II Law of Thermodynamics refers to everything and is absolutely the most important law in physics. It fact it is Newton's Laws of Motion as it is kinetic motion of molecules. The very basic one will be vibration. If we sink into atomic level we can even say to electromagnetic field of electron shells because this the only space of contact. Proven in every possible way. Nevertheless, the modern accepted astrophysics is so wrong with this law. Quantum physics also can't handle this law correctly. But at our human scale this law is so damn horribly true at every instance.
