Latent heat is:

released from a vapor when it condenses. released from a liquid when it freezes. absorbed by a solid when it sublimes.

Explanation:

Matter needs to absorb or release heat in order to change from one state to another. This heat is known as latent heat because it is not used to raise the temperature (thus it is not recorded) but it is used for the state change.

When matter passes from a low energy state to a high energy state (solid ⇒ liquid ⇒ vapor) it absorbs heat, which results in higher kinetic energy of the molecules.

When matter passes from a high energy state to a low energy state (vapor ⇒ liquid ⇒ solid) it releases heat, and the molecules have less kinetic energy.

Therefore, latent heat is:

released from a vapor when it condenses. released from a liquid when it freezes. absorbed by a solid when it sublimes.
