Question

what is vapour pressure and how it is affected by intermolecular forces.​

Answer 1

Answer:

Vapor pressure is a property of a liquid based on the strength of its intermolecular forces. A liquid with weak intermolecular forces evaporates more easily and has a high vapor pressure. A liquid with stronger intermolecular forces does not evaporate easily and thus has a lower vapor pressure.

Answer 2

Explanation:

$\sf{hey\:}$ $\sf\cancel{mate\:Here\:}$ $\sf\red{is\:ur\:answer}$

A liquid's vapor pressure is directly related to the intermolecular forces present between its molecules. The stronger these forces, the lower the rate of evaporation and the lower the vapor pressure.
