Final answer:
When the pressure of a liquid is decreased, the vapor pressure decreases, resulting in an increase in the boiling point of the liquid.
Step-by-step explanation:
When the pressure of a liquid is decreased, the vapor pressure of the liquid also decreases. The decrease in vapor pressure is related to the strength of the intermolecular forces in the liquid. In this case, a decrease in pressure is likely to result in an increase in the boiling point of the liquid. This is because the higher boiling point is due to the stronger intermolecular forces between molecules in the liquid, which require more energy to break and allow the liquid to turn into gas.
