Phase Change & Latent Heat

When a substance changes phase (e.g., from solid to liquid), it absorbs or releases heat without changing its temperature. This energy is called latent heat. The formula Q = mL relates the heat energy (Q) to the mass (m) and the specific latent heat (L) of the substance.
