GENERAL KNOWLEDGE

Detailed explanation-1: -At this point, the solid melts into liquid. The temperature at which this change from solid to liquid happens is called the melting point. Each solid has a set melting point at normal air pressure.

Detailed explanation-2: -The melting point of a compound is the temperature at which it changes from a solid to a liquid. This is a physical property often used to identify compounds or to check the purity of the compound.

Detailed explanation-3: -When a solid is heated, the particles gain sufficient energy to break away from one another and move past each other. The change from solid to liquid is called melting or fusion.

Detailed explanation-4: -Answer: Solution: In the process, the change from the solid state to the liquid state on heating at a fixed temperature is called melting. Melting point can be defined as the fixed temperature at which a solid starts changing to its liquid state.
