Question

How does melting point of solid indicate the strength of its intermolecular forces of attraction?​

Answer 1

Explanation:

If Intermolecular force of attraction is strong then Melting point is also high because more heat is use to melt down it.

Answer 2

Let's see the relation:

$\cdot{ \bf{ \purple{Melting \: point \: \& \: Intermolecular \: force }}}$

For a substance, the force of attraction between their particles (Atom or molecules) determines the strength of bonding. More is this strength, more it will difficult to melt the body (Converting from one state to another).

It's because....

• Melting is a process of converting a state of matter into another state i.e. From solid to liquid.
• Here we are breaking the force of attraction to increase the voids, So that it gets converted to liquid state.
• Hence, we can say that melting point is directly proportional to intermolecular force of attraction.
• More is the force of attraction, more efforts will be needed to melt it. For this, we increase the temperature.

This also increases the boiling point of the substance. The intermolecular forces determines how easily we can change its state by increasing the temperature.
