  • Phase Change and Latent Heat

    In thermodynamics, phase change refers to the transition of a substance from one state of matter (solid, liquid, or gas) to another. These changes are associated with energy transfer, commonly in the form of heat, without a change in temperature. The energy required or released during a phase change is known as latent heat. Phase…
