Solution

1. Freezing of water is an exothermic process, thus when water bodies freeze, the weather becomes warm around it due to the energy so released by the water body.

2, This is because, when water freezes to ice, intense H-bonding takes place in the process, leading to higher stability.

3. Thus, it is a universal fact that stability is accompanied by release in energy, thus we observe a warm weather when a water body freezes.
