## Residual Entropy

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

### Re: Residual Entropy

Residual entropy is the difference between entropy not at equilibrium and the state that the molecule is closest to zero (temperature). It is just a way to measure entropy which is ultimately a way to measure work.

### Re: Residual Entropy

Residual entropy just means the randomness of the system based on the position of the elements/molecules inside of it, when there is no movement (temperature is K=0).

### Re: Residual Entropy

Think of residual entropy as something that is completely unmoving, something without thermal energy, rotational motion, or translational motion.
