Why is lower boiling point associated with higher 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. … Thus, the temperature of the boiling point must be increased.
Why does low boiling point mean high vapor pressure? If the intermolecular forces are small, the liquid has a high vapour pressure. Little heat energy will have to be added to separate the molecules, so the boiling point will be low. … More heat will be required to separate the molecules, so the boiling point will be higher.
How is boiling point related to vapor pressure? 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.
Does a higher boiling point have higher vapor pressure? The higher the vapor pressure of a liquid at a given temperature, the lower the normal boiling point (i.e., the boiling point at atmospheric pressure) of the liquid. The vapor pressure chart to the right has graphs of the vapor pressures versus temperatures for a variety of liquids.

What temperature/pressure does water boil at sea level?
A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude. For a given pressure, different liquids will boil at different temperatures.
