Question

Quizplus · Accepted Answer

Vapor pressure is the pressure exerted by a gas above the surface of its liquid. It is the result of the molecules in the liquid being in constant motion and some of them escaping into the gas phase. The vapor pressure increases with temperature and is a measure of the tendency of the liquid to evaporate.
