If heat is released from water, what phase change occurs?

Explanation:

It is known that in order to break the bonds in a substance we need to provide it heat energy. Hence, energy will be absorbed by the molecules then and they will move far apart from each other.

Due to this solid state of water will change into liquid state.

On further heating, liquid state of water will change into vapor state.

But when liquid state of water will change into solid state then water molecules need to release energy due to which there occurs decrease in their kinetic energy.

Hence, the molecules will come closer to each other. As a result, liquid state of water will change into solid state (ice).

Thus, we can conclude that if heat is released from water, then phase change occurs from liquid to solid.
