WebJun 17, 2024 · Phase transitions play an important theoretical and practical role in the study of heat flow. In melting (or “fusion”), a solid turns into a liquid; the opposite process is freezing.In evaporation, a liquid turns into a gas; the opposite process is condensation. A substance melts or freezes at a temperature called its melting point, and boils … WebA phase change is a physical process in which a substance goes from one phase to another. Usually the change occurs when adding or removing heat at a particular temperature, known as the melting point or the boiling point of the substance.
