Boiling Point vs Melting Point

[MaryBanh_2K]

From my understanding, the boiling point and melting point both increase as the intermolecular forces increase in strength but what is the difference between the two?

You're correct about the melting and boiling point increasing with stronger intermolecular forces. The difference between the two is that when melting, a substance goes from a solid to a liquid and in boiling, a substance goes from a liquid to a gas. Usually boiling requires more energy than melting.

The graph on the above website illustrates the relationship between the three main states of matter (solid, liquid, gas) and the melting and boiling points. Usually, the straight line is longer at the boiling point to show that it takes more time and energy to break the bonds compared to melting where the bonds are weakened.

You're right that the boiling and melting point of a molecule deals with the intermolecular forces. However, melting deals with the change of a solid into a liquid. And boiling is the vaporization of a liquid.

Boiling means to transform a liquid substance into vapor or gas.
Melting means to transform from a solid state of matter to liquid.

When it comes to measuring IM force strength, they mean the same thing. The higher point means that the molecule has stronger IM forces.

Boiling point and melting point can both act as indicators of the relative strength of intermolecular forces and are closely related. The difference between the two lies in the phase or state of the compound. Thus, a boiling point is the temperature that a liquid turns to gas, and a melting point is the temperature that a solid turns to liquid. Boiling points are thus higher than a melting point.
