Whose molecules: liquid water at \[\mathbf{0}{}^\circ \mathbf{C}\] or ice at \[\mathbf{0}{}^\circ \mathbf{C}\] have greater potential energy? Give reason.

Answer:

                Water molecules possess more potential energy. The heat given to melt the ice at \[0{}^\circ \text{C}\] is used up in increasing the potential energy of water molecules formed at \[0{}^\circ \text{C}\].
