Question

Quizplus · Accepted Answer

The phase change from liquid to solid releases energy, as it involves the molecules losing energy and slowing down to form the more ordered and stable solid phase. The other options involve phase changes that either require energy input (such as melting from solid to liquid) or do not release or require energy (such as gas to liquid or solid to gas).
