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

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.
