The entropy of a system is a measure of the amount of thermal energy in a system that is unavailable for doing useful work. When the temperature of a crystal is increased, the thermal energy of the crystal increases, leading to an increase in the entropy of the system. This means that the crystal becomes less ordered and more disordered as its temperature increases, resulting in an increase in ΔS.
