Phase change can be in the following forms: solid-solid, solid-liquid, solid-gas, liquid-gas and vice versa. In several transitions, such as solid-solid, heat is stockpiled as the material is altered from one crystalline to another. These transitions generally have smaller latent heat and ...

Liquid crystal is a state of matter - like liquid, solid, and gas. The term “liquid crystal” is used to denote a material that exhibits a liquid phase under certain conditions. To understand what differentiates a liquid crystal phase from a liquid or s
1. What Is Melting Point? Melting point is a characteristic property of solid crystalline substance. It is the temperature at which the solid phase changes to the liquid phase. This phenomenon occurs when the substance is heated. During the melting process, all of the energy...
