When a liquid is in equilibrium with its vapor in a closed container:
A)the rate at which molecules from the liquid phase enter the gas phase exactly equals the rate at which molecules from the gas phase pass into the liquid phase
B)a change in temperature will not change the pressure in the container
C)the amount of gas in the container must exactly equal the amount of liquid
D)molecules cannot go from the liquid phase to the gas phase because the amount of liquid in the container is constant
E)the vapor will gradually change back to the liquid state,that is,no vapor will be left

In equilibrium, the rate of molecules entering the gas phase from the liquid is equal to the rate of molecules returning to the liquid phase, which is also known as the rate of condensation. This creates a dynamic balance between the liquid and vapor phases, and the amount of gas in the container can exceed the amount of liquid. Temperature can affect the equilibrium, but it does not change the pressure, and the vapor will not completely return to the liquid state unless the conditions change.
