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.
