The 16O evaporates ___ than 18O,and condenses___ .

Question

Quizplus · Accepted Answer

Oxygen-16 (16O) has a lower atomic weight and smaller size than oxygen-18 (18O). This means that 16O molecules have weaker intermolecular forces and are more likely to evaporate than 18O molecules. Therefore, 16O evaporates more easily than 18O. On the other hand, 16O molecules have a harder time condensing because they are more likely to escape into the atmosphere. This means that 18O condenses more easily than 16O. Therefore, the correct choice is C: 16O evaporates more easily and condenses less easily than 18O.
