Hmm, if you increase the temperature, the kinetic energy of molecules in the calorimeter should be increased, and potential energy is stayed constant.Particles move faster,  <c^2> increased. Internal energy increased.

But if you're talking about the water, as lattice structure is 'formed'/bonds formation/forces between molecules increased. So, no change in kinetic energy, potential energy decreases, internal energy decreases for water.
