Entropy is a Mathematical Expression

Entropy is a Mathematical Expression . Therefore there is no need to invent any special physical explanation. Jozsef Garai Dept. of Earth Sciences. The macroscopic determination of entropy first was expressed by Clausius in 1865. S = Entropy Q = Heat T = Absolute Temperature.

Entropy and the Driving Force

Entropy and the Driving Force. Each substance has its own entropy value. This is an absolute scale, because a perfectly ordered substance at 0 K has an entropy of 0. Compare this to enthalpy, where only changes, ? H, can be measured. Some entropy values. Temperature effects on entropy .
