Absolute Entropies The entropy of a substance increases as the temperature is increased. This is readily understood because the addition of heat to a substance results in an increase in molecular randomness. Conversely cooling a substance makes it more ordered and decreases its entropy.

Unformatted text preview: At absolute zero, the entropy of a perfect crystalline substance may be taken as zero. This statement is sometimes called the Third Law of Thermodynamics . On the basis of the third law, absolute entropies can be calculated from heat capacity data by extrapolating to absolute zero....
