Answer 1

1️⃣Melting point of substance is the temperature at which solid changes into liquid. 

2️⃣Melting point tells about the strength of force of attraction present between the particles.

3️⃣If forces of attraction between the molecules are strong then melting point is very high and if the forces of attraction are weak between the molecule then melting point will be less.

Answer 2

Melting point of a solid is that temperature when a substance changes it's physical state from solid to liquid stare at standard or normal pressure of 1 atm.

Melting point signifies the strength of the force of attraction between the particles of the solid.
