At what phase is the heat capacity the greatest? Is it when the substance is a solid, liquid or gas? Please also explain why.

I believe that the heat capacity is the greatest when the subastance is a solid.

For water the heat capacity is the greatest when it is a liquid. However is not water an exception? What is the overall rule?
