Entropy S, doesn't really have an "application". It is one of the fundamental state functions in thermodynamics, and ranks alongside, E, P, V, T
Traditionally termed a measure of disorder, a more understandable description is that it is a measure of how energy is spread over energy micro-states.
Entropy is not change. Entropy is disorder.
It's not that entropy can't be reversed, it's that the entropy of the universe is always increasing. That means that while you can reduce the entropy of something, the entropy of another thing must go up even more so that in total, the entropy goes up.
The entropy of the universe is increasing
No, entropy is a state function.
positive
This is called entropy.
Entropy is not change. Entropy is disorder.
The entropy increases.
Entropy is the measure of system randomness.

Certain variables in thermodynamics are hard to measure experimentally such as entropy. Maxwell relations provide a way to exchange variables

No, entropy is a state function.
It won't. Entropy always increases.
positive
Entropy is a measure of the disorder or randomness in a system. The phase of matter with the highest entropy is generally considered to be the gas phase, as the particles in a gas have the highest degree of freedom and randomness compared to liquids and solids.
