How intermolecular and pressure vapor can affect by boiling point? The lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil. As a liquid is heated, its vapor pressure increases until the vapor pressure equals the pressure of the gas above it. … The temperature of a boiling liquid remains constant, even when more heat is added.
How do intermolecular forces affect vapor pressure and boiling point? Higher the intermolecular forces between the liquid particles, harder it is for it to escape into the vapor phase, ie., you need more energy to convert it from liquid to the vapor phase, in other words, higher its boiling point.
How does boiling point affect vapor pressure? Lowering the vapor pressure of a substance has an obvious effect on boiling point; the boiling point goes up. The BP increases because more energy is required for the solvent’s vapor pressure to reach the external pressure.
How does boiling point affect intermolecular forces? The overarching principle involved is simple: the stronger the noncovalent interactions between molecules, the more energy that is required, in the form of heat, to break them apart. Higher melting and boiling points signify stronger noncovalent intermolecular forces.

Why boiling point increase with pressure?
