Answer to Question 1

ANS: D
The warmer the air, the more vapor it can hold. Specifically, the capacity of air to hold water va-por increases with temperature. The warmer the air making contact with a water surface, the fast-er is the rate of evaporation.

Answer to Question 2

ANS: B
Water vapor pressure represents the kinetic activity of water molecules in air.
