Quizplus · Accepted Answer

Boiling water is a physical change because it involves a change in the state of matter (from a liquid to a gas) but does not result in a change in the chemical composition of water. Decomposition of a dead organism, on the other hand, is a chemical change because it involves the breakdown of complex organic molecules into simpler ones, resulting in a change in the chemical composition of the organism.
