Why is the entropy of vaporization of a material always smaller than its entropy of fusion?
A) Because it involves a less disordered product.
B) Because it involves a less disordered starting material.
C) Because gases are always smaller in density than their corresponding liquids or solids.
D) It is not; it is always larger.
