In which liquid do molecules leave the surface more easily?
Answer and explanation
Correct answer: In a liquid with higher vapour pressure
Molecules leave the surface during evaporation. At the same temperature, a liquid with higher vapour pressure has a greater equilibrium tendency to enter the vapour phase, indicating that its molecules escape more readily. A low-vapour-pressure or non-volatile liquid has stronger retention in the liquid phase; a frozen substance is not the relevant liquid comparison.
