Question

Hey users!!

How does melting point of a substance indicate the strength of its forces of attraction?

Plz explain properly...

Answer 1

when we provide heat to a substance its molecules started vibrating faster and faster hence temperature increases now after reaching to its melting point the temperature remains constant because now the heat provided is now used to overvome force of attraction( making weak to interparticle force) now the substance changes its phase like solid to liquid.
Ex- temperature of ice is -20 degree Celsius when we provide heat its temperature rises and reach to its melting point (0 degree celsius ) it started melting.

So higher the melting point higher will be interparticle force

Answer 2

Explanation:

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.
