Because water molecules can form a variety of hydrogen bonds
with each other, water molecules tend to have more configurations
when they are by themselves than when they are mixed with other
molecules that cannot form hydrogen bonds. Imagine that the
interactions between water molecules and the molecules of a non
polar substance A (W-A interactions) are stronger than the W-W and
A-A interactions. In this case one can predict that:
