c.water heats.
This is due to the Latent Heat of Vaporisation.
Latent heat of vaporization is a type of physical property of all substances.
It can be defined as the heat needed to change a mole of liquid at its boiling point at the standard atmospheric pressure.
It is denoted in kg/mol or kJ/kg.
When any material in a liquid state is provided energy, there is a change in phase from liquid to vapor and the energy that is absorbed in the process is known as heat of vaporization.
