Which body has the greatest internal energy: a piece of ice at a temperature of O ° C

Which body has the greatest internal energy: a piece of ice at a temperature of O ° C or the water obtained from this piece of ice at O ° C?

If you take a piece of ice and water of the same mass, then the internal energy of the water will be greater, because in order to destroy the crystal lattice near the ice and turn it into water, you need to spend energy. It turns out ice + energy for the destruction of the crystal lattice = water, it is obvious that the internal energy of water is greater. In the end, a proof can be given: the h20 molecules in the form of ice hardly move, and the molecules of liquids are in constant motion, that is, the kinetic energy of molecules in water is greater than that of molecules in ice.
