At what phase is the heat capacity the greatest?

Click For Summary
SUMMARY

The heat capacity of a substance varies with its phase, being greatest in the liquid state for most substances, including water. While solids generally have lower heat capacities due to their fixed structure, liquids can absorb more heat energy as they transition between states. Water is a notable exception, exhibiting a high heat capacity in its liquid state, which is crucial for temperature regulation in natural systems. The overall rule is that liquids typically have higher heat capacities than solids and gases.

PREREQUISITES

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.

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