## disorder & entropy

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

### disorder & entropy

What does an increase in disorder correspond to? An increase or decrease in entropy?
And why?

### Re: disorder & entropy

An increase in disorder would correspond to an increase in entropy, since entropy is the number of different states a system can be in. For example, when a substance goes from a liquid to a gas, there is an increase in entropy of the system, since the collection of gas molecules can occupy a greater number of states. This also corresponds to an increase in disorder of the system.

Adding on, the equation S=KblnW shows that with more microstates (W=number of microstates^# of particles in the system), there is an increase in entropy.
