Does condensation heat or cool the surface?

Explanation:
Condensation releases latent heat. When water vapor turns into liquid, the energy used to vaporize it is released as heat. That heat is transferred to the surface where the vapor is condensing, warming it. Because the latent heat of condensation is substantial, even a small amount of condensation can noticeably raise the surface temperature. In contrast, evaporation would cool the surface by absorbing heat, so condensation heats the surface.
