Can energy be absorbed when matter changes?

Answer 1

Yes, energy can either be absorbed or given off when matter changes state, while the temperature of the system remains constant

Endothermic changes are those in which energy is absorbed; melting ice into water, boiling water into steam, and sublimating ice into steam are a few examples of possible state changes that show endothermic changes.

Exothermic changes are those in which energy is released. Condensation of steam into water, freezing of water into ice, and deposition of steam into ice are a few states that could exhibit exothermic changes.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
