    Melting, change of a solidinto a liquid when heat is applied. In a pure crystalline solid, this process occurs at a fixed temperature called the melting point; an impure solid generally melts over a range of temperatures below the melting point of the principal component. Amorphous (non-crystalline) substances such as glass or pitch melt by gradually decreasing in viscosity as temperature is raised, with no sharp transition from solid to liquid.

    1Thank You

    • Diffusion is the movement of particles from a high concentration to a low concentration. Brownian motion is the diffusion of many particles.

    • Melting point is the temperature at which a solid changes its phase to become a liquid. The process is called melting.

    4Thank You
