  Explain what happens to the molecular motion and energy of 1 kg of water at 273 K when it is changed into ice at same temperature. How is the late heat of fusion related to the energy exchange that takes place during the change of state?

Answer:

    ·         Molecular motion decreases as water gets converted into ice. ·         Latent heat of solidification is given off. ·         Latent heat of solidification is equal to latent heat of fusion.
