Consider a sample of water in a closed, rigid container. Which of the following will indicate that the given physical process has reached equilibrium?

Question

Quizplus · Accepted Answer

Option A is incorrect as the mass of the container does not provide information about the equilibrium state. Option C is incorrect as an increase in the volume of water would mean that the equilibrium has not been reached. Option D is incorrect as only option B indicates equilibrium, i.e., the rate of evaporation and condensation of water molecules has become equal, thereby maintaining a constant vapor pressure in the container.
