Each particle has a position, a mass, and a velocity. I know that temperature is the average kinetic energy of all the particles, so temperature is no problem to calculate. But, how would you calculate the entropy of the particles? S = k ln(number of states) dS = dQ / T Any help is appreciated. -Rick Giuly If replying by email please use: rgiuly at ucsd dot edu reference:http://en.wikipedia.org/wiki/Lennard-Jones_potential The problem I have with S = k ln(number of states) is that it seems like the number of states is nearly infinite, since there are multiple particles and each can be at any location in space. dS = dQ / T This formula tells me so
