WebJul 10, 2024 · As their name suggests, phase change materials change their physical state in response to heat. That is, they convert from solid to liquid when they store heat, and liquid to solid when they release their stored energy. WebSince the energy involved in a phase changes is used to break bonds, there is no increase in the kinetic energies of the particles, and therefore no rise in temperature. Similarly, …
