## Molar Entropy

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

### Molar Entropy

How does one know when a substance has a high molar entropy?

Generally, more complex molecules have higher molar entropy. Also, molar entropy is proportional to the heat required to raise a substance to a certain temperature.
--> Entropy = heat required/final temperature

### Re: Molar Entropy

The molar entropy would also increase as a substance goes from solid to liquid to gas.

### Re: Molar Entropy

Molar entropy is the amount of disorder in a system. You can imagine gas particles have more disorder than solid particles because of the distance between them so as stated in a previous response entropy would increase as a substance transitions from solid to liquid to gas.
