Which of the following statements is true of vapor pressure?
A) It is the energy required to increase the surface area of a liquid.
B) It is the partial pressure of a gas in equilibrium with its liquid form in a closed container.
C) It decreases as the temperature of a liquid increases.
D) It causes a drop of a liquid to minimize its surface area.

Question

Quizplus · Accepted Answer

Vapor pressure is the pressure exerted by the gaseous form of a substance in equilibrium with its liquid form in a closed container. It is dependent on temperature and the force of attraction between particles in the liquid phase. As temperature increases, vapor pressure increases. Option A describes surface tension, option C describes the boiling point, and option D describes the phenomenon of surface tension causing liquids to form spherical shapes.
