The entropies of substances tend toward zero as absolute zero temperature is approached, or as Lewis and Randall expressed it:

If the entropy of each element in some crystalline state may be taken as zero at the absolute zero of temperature, every substance has a finite positive entropy, but at absolute zero, the entropy may become zero, and does so become in the case of perfectly crystalline substances.
