Phase Change Materials and Its Applications | SpringerLink
Materials undergo phase transition when the heat is absorbed or released. This occurs mostly at a constant temperature, for pure substances, known as the melting or boiling point, depending it is a solid–liquid or liquid–gas phase transition. The process solid–liquid phase transition can be understood from Fig. 13.1. Fig. 13.1.
