Is the boiling of water a heating or cooling process on the water and why?

A

Heating $-$ Boiling water occurs when water molecules phase change from a liquid to a gas and leave the water. These leaving gas molecules result in a decrease in the water's energy and boiling is thus considered a heating process.

B

Heating $-$ Boiling water occurs when water molecules phase change from a liquid to a gas and leave the water. These leaving gas molecules result in an increase in the water's energy and boiling is thus considered a heating process.

C

Cooling $-$ Boiling water occurs when water molecules phase change from a liquid to a gas and leave the water. These leaving gas molecules result in an increase in the water's energy and boiling is thus considered a cooling process.

D

Cooling $-$ Boiling water occurs when water molecules phase change from a liquid to a gas and leave the water. These leaving gas molecules result in a decrease in the water's energy and boiling is thus considered a cooling process.
