The temperature at which a solid melts to become a liquid at the atmospheric pressure is called its melting point. The melting point of a solid is an indication of

Melting point is the temperature at which a solid changes into liquid at atmospheric pressure.

If a solid has strong intermolecular forces of attraction, more heat energy is required to overcome these forces, therefore its melting point will be higher.

If the intermolecular forces are weak, less heat energy is required, and the melting point will be lower.

Thus melting point basically reflects how strongly the particles of a substance attract each other.

Hence it indicates the strength of intermolecular forces of attraction.
