Question:
Why is water a liquid at room temperature? At first this question seemed easy enough, but research on the Internet has not provided me any help. Can you help?

Your question is a special case of a more general one: "Why does substance X melt at its melting point?" The answer, which is not much help, is no one knows. An "answer", which really begs the question is that a substance melts when the thermal energy is sufficient to cause molecules to move from their location in the crystal lattice. However, predicting what that temperature is, is not solved.

Aaron,

The hydrogen bonds in water are chemical bonds that form between molecules containing a hydrogen atom bonded to a strongly electronegative atom. In this case, this strongly electronegative atom is oxygen. It is this hydrogen bonding that makes water from a liquid at room temperature. I hope that this helps.

Sincerely,

Bob Trach
