Question

15. Zeroth law of Thermodynamics is :
(A) Kinetic energy of molecules of a gas is zero.
(B) Ideal gas does not contain molecules.
(C)
If two systems are seperately in thermal equilibrium with a third system, then they themselves are in
thermal equilibrium with each other.
(D) Absolute zero temperature cannot be attained.​

Answer 1

Answer:

Law of Thermodynamics

Thermodynamics is a very important branch of both physics and chemistry. It deals with the study of energy, the conversion of energy between different forms and the ability of energy to do work. As you go through this article, I am pretty sure that you will begin to appreciate the importance of thermodynamics and you will start noticing how laws of thermodynamics operate in your daily lives! There are essentially four laws of thermodynamics.

Zeroth Law of Thermodynamics

“If two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with one another”

Let’s first define what ‘thermal equilibrium’ is. When two systems are in contact with each other and no energy flow takes place
