Working theory:
PCM stands for Phase Change Material. It refers to a type of material that has the ability to change from one physical state to another at a specific temperature, while absorbing or releasing a significant amount of latent heat during the phase transition. This property allows PCM materials to store and release thermal energy as they undergo these phase changes.
The temperature at which a PCM transitions from one phase to another is known as its phase change temperature.
