In physics, binding energy (also called separation energy) is the minimum energy required to disassemble a system of particles into separate parts. This energy is equal to the mass defect minus the amount of energy, or mass, that is released when a bound system (which typically has a lower potential energy than the sum of its constituent parts) is created, and is what keeps the system together.

This then implies that the entropy of the system is given by: where c is some constant. The value of c can be determined by considering the limit T → 0. In this limit the entropy becomes S = klog Ω0 where Ω0 is the ground state degeneracy. The partition function in this limit is where U0 is the ground state energy. Thus, we see that c = 0 and that:
