Question

Quizplus · Accepted Answer

The vapor pressure of a liquid is the pressure of the gas phase above its liquid phase at equilibrium. This means that molecules of the liquid are escaping into the gas phase and the gas phase is also condensing back into the liquid phase at an equal rate, so there is a balance between the two phases. Therefore, the answer is C, which is "gas above its liquid".
