Is some heat released or absorbed by condensation, boiling and evaporation?

Since the liquid during evaporation leaves the fastest particles with higher kinetic energy, the internal energy of the liquid decreases. Consequently, in general, the energy of the evaporating liquid decreases, heat is absorbed.
Condensation always occurs with the release of an amount of heat (since the internal energy of a substance decreases). That is, the temperature of the surrounding bodies will rise (the liquid transfers excess energy to the surrounding bodies).
Boiling occurs with the absorption of heat. Most of the supplied heat is spent on breaking the bonds between the particles of the substance, and the rest on the work done during the expansion of the vapor. As a result, the interaction energy between vapor particles becomes greater than between liquid particles, therefore the internal energy of vapor is greater than the internal energy of a liquid at the same temperature.
