The water particles in the air above the cup will be moving faster compared with the water particles in the cup which are closer together (Option a)
- Water molecules in liquid state are compactly packed as compared to the water molecules in the vapor state. Because the intermolecular forces of attraction are greater in liquids than vapors.
- Therefore, the constituent particles of liquid, on gaining energy, convert into vapors which can move about more freely.
