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 latent heat of fusion related to the energy exchange that takes place during this 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.
