Question

What is change in internal energy for melting of ice

Answer 1

potential energy is absorbed

Answer 2

hay mate

here is your answer

The internal energy of every chemical species differs from that of every other chemical species. So, if you have a combination of species, even under ideal gas conditions, the combined internal energy depends on the number of moles of each chemical species. If the number of moles of the various chemical species changes, for example if reacting species convert into product species, the internal energy of the combination changes. To keep the temperature constant, you would have to remove or add heat, depending on if the reaction is exothermic or endothermic.
