This document discusses how heat can change matter and be used. Heat can change matter from one state to another, such as freezing liquid water into ice or evaporating liquid water into a gas. Heat is a form of energy and can come from sources like the sun, fire through burning fuels, electricity, and friction. Heat moves from warmer objects to cooler ones and can change the properties of materials, such as hardening clay in a kiln.
