(a)
Interpretation:
The entropy changes in the given processes has to be explained.
Concept Introduction:
In
The SI unit of entropy is J/K.
(b)
Interpretation:
The entropy changes in the given processes has to be explained.
Concept Introduction:
In thermodynamics entropy refers to randomness of the system. Second Law of thermodynamics sates that the entropy of the universe is increasing. That is, the system is always tending to have more disorders in it. Let us consider the example of diffusion of gas molecule to understand the concept of entropy. When a perfume bottle is opened the fragrance is immediately spread into the surroundings. Inside the bottle the gas molecules are close to each other and entropy is less. Once the bottle is opened the gas molecules escapes into the surroundings and have more disorderly arrangements.
The SI unit of entropy is J/K.
