Question

The melting point of a solid is an indication of the strength of the force of attraction between its particles.

• A. True
• B. False

Answer 1

The correct option is A

True

On supplying heat to the solids, the kinetic energy of the particles increases. Due to the increased kinetic energy, particles start vibrating with greater speed. The energy supplied by heat overcomes the forces of attraction between the particles. A stage is reached when the solid melts and become liquid. This point is termed as the melting point. Hence, this point can be used as an indication of the strength of forces of attraction between its particles. Greater the force of attraction, higher is the melting point.
