1. a(n)__________________________change releases energy.

Explanation:

An exothermic change is a type of change (either physical or chemical) where energy is released. For example, burning a fuel (a chemical change) releases heat (energy), and some physical changes like freezing (where heat is given off as a substance changes from liquid to solid) can also be exothermic. The key characteristic is the release of energy, which is what the word "exothermic" describes.

Answer:

exothermic
