What is the relationship between the vapor pressure ,intermolecular force,boiling point, temperature
Accepted Answer
Boiling point is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. Vapor pressure of a liquid is defined as the pressure exerted by the vapor of that liquid when it is in equilibrium with the liquid. Intermolecular forces refer to the attractive forces that act between molecules. The stronger the intermolecular forces, the lower the vapor pressure of the liquid at a given temperature. This is because stronger intermolecular forces hold the molecules more tightly together, making it more difficult for them to escape into the vapor phase. Consequently, liquids with strong intermolecular forces will have higher boiling points than liquids with weak intermolecular forces because more energy is required to overcome the intermolecular forces and cause the liquid to boil.
