A phase-change material (PCM) is a substance which releases/absorbs sufficient energy at phase transition to provide useful heat or cooling. Generally the transition will be from one of the first two fundamental states of matter - solid and liquid - to the other. The phase transition may also be between non-classical states of matter, such as the conformity of crystals, where the materi…
A phase change material (PCM) is a substance that absorbs and releases thermal energy over a period of time. PCMs work by undergoing the processes of melting and solidifying to store and dispense heat. Thermal engineers use these materials in a variety of applications, including thermal insulation and thermal management.
Phase change materials absorb thermal energy as they melt, holding that energy until the material is again solidified. Better understanding the liquid state physics of this type of …
