Document Summary
Celsius, but it is very unlikely because molecules are not going to tend to lose that energy. However, if we have an ice cube at 20 degrees, it is very likely that is will melt spontaneously into water. We will later attempt to define entropy in a thermodynamic sense: statistical definition of entropy, case study, say there is a cylinder with helium atoms. V1, the full cylinder is known as v2. The chances of finding a he atom in. If there is only one atom, the chances of finding the he atom in v1 is . 5: however, if there are two atoms, there are two ways for an atom to be in. For both of them to be in v1 the probability is: w = (. 5 * . 5) = 0. 25. If v2 had one mole of molecules, the chance of finding all of them in v1 would be practically impossible: this tells us something very important:
