Answer to Question 1

ANS: D
To be distinguished from visible particulate water, such as mist or fog, this invisible gaseous form of water is called molecular water. Molecular water obeys the same physical principles as other gases and therefore exerts a pressure called water vapor pressure.

Answer to Question 2

ANS: B
As the surrounding air loses heat energy, it cools. This is the principle of evaporation cooling.
