Imagine that 1.00 mol H2O(l) is placed in a piston with a constant external pressure Pext = 1 bar. The piston is then placed in a large thermal bath at a temperature of 270 K. Let water be the system. Using relationships derived in class, one can calculate that the freezing of water (to form ice, a crystal) is ?G = -65 J and ?S = -21 J/K. A student claims that this process cannot be spontaneous, because S must increase for a spontaneous process. Is the student correct? If so, why? If not, why not?
