This BBC Bitesize resource explains how matter changes between solid, liquid, and gas states through processes such as melting, freezing, evaporation, condensation, and boiling. Students explore how energy and particle motion influence phase changes while building connections to kinetic molecular theory and the behaviour of matter.
