A sample of gas is cooled to its vapourization temperature. What is true before the sample reaches equilibrium between the liquid and gaseous phases?

Question

Quizplus · Accepted Answer

When a gas is cooled to its vaporization temperature and before equilibrium is reached, more molecules are condensing than vaporizing. This is because the system is transitioning from a gaseous state to a liquid state, leading to a net increase in the number of liquid molecules as they lose energy and condense.
