Which of the following processes must exist in equilibrium with the evaporation process when a measurement of vapor pressure is made?
A)fusion
B)vaporization
C)sublimation
D)boiling
E)condensation

Question

Quizplus · Accepted Answer

When a measurement of vapor pressure is made, the process of evaporation must be in equilibrium with the process of condensation. This is because vapor pressure is defined as the pressure exerted by the vapor of a substance when it is in equilibrium with its liquid or solid state. Therefore, the only choice that fits with this definition and logic is E) condensation.
