Question

the melting point of a solid is an indication of the streangth of the force of attraction between its particals...plz any one explain me how?

Answer 1

Heya frnd.....

Yes that's true lesser the force of attraction lesser will be its melting and higher the force of attraction between molecules higher is the melting point

Answer 2

Melting point of a solid is defined as the temperature at which a solid changes into a liquid. Melting point of a solid indicates the strength of the force of attraction between the particles of the solid. On heating a solid, its molecules absorb energy in the form of heat and their kinetic energy increases.

As the kinetic energy increases, the temperature of the solid increases. As a result, the force of attraction between the molecules decreases and the molecules become more and more separated. This increases the potential energy of the molecule and the particles leave their fixed positions and start moving more freely.
Hope it help
