... Why is S(H2O(l) > S(H20(g)? It is better to speak of entropy as a measure of the amount of energy in a system that cannot be used to do work rather than an overly simplistic "measure of disorder". Recall that the units of entropy in the SI system are Joules/Kelvin (the units of heat capacity). From ...
