Final answer:
Condensation occurs when heat energy is released from vapor, increasing the temperature of the surroundings. It usually happens on cold surfaces. The heat energy released during condensation can be calculated using the formula Q = mLy.
Step-by-step explanation:
When you release the heat energy from vapor, it is referred to as condensation. During condensation, heat is transferred from the vapor to the surroundings, increasing the temperature of the surroundings.
This is why condensation usually occurs on cold surfaces.
The heat energy released during condensation can be calculated using the formula Q = mLy, where Q is the heat energy, m is the mass of the condensing substance, and Ly is the latent heat of vaporization.
