## Entropy [ENDORSED]

Volume: $\Delta S = nR\ln \frac{V_{2}}{V_{1}}$
Temperature: $\Delta S = nC\ln \frac{T_{2}}{T_{1}}$

### Entropy

Is entropy a state function?

### Re: Entropy

Yes, entropy is a state function, because the it describes the equilibrium state of a system, regardless of how it got to that state.

### Re: Entropy

Every state has a finite value for the state function entropy S(A). The difference of entropy between two states is delta S = S(B) - S(A)
There are many different reversible pathways between two different states. But state function does not depend on the paths it goes from one state to another. It just depends on the final and initial state of the system.

### Re: Entropy  [ENDORSED]

Yes, it is a state function like enthalpy because it isn't dependent on the path taken to obtain the state it is in.
