Question

Why speicific heat of water first decrease and the increase with the increase in temperature?

Answer 1

Answer:

The heat goes first into increasing the kinetic energies of the molecules. ... As the substance heats up, the average kinetic energy of the molecules increases. The collisions impart enough energy to allow rotation to occur. Rotation then contributes to the internal energy and raises the specific heat.

Answer 2

Answer:

Because water has a high heat capacity, increasing the temperature by one degree requires more energy. The sun sends out a more or less constant energy level which heats up sand faster and water faster.
