### Types of Entropy

Hi! Can someone please explain the difference between statistical entropy and residual entropy? I'm having a hard time grasping this concept. Thanks.

### Re: Types of Entropy

Hey!

Statistical entropy (S) is defined by: S= kln(W), where W shows the number of different states where a system can exist in. Residual entropy calculates the number of states/entropy of a system that has near zero energy. The entropy at ≈zero Kelvin is residual entropy.
