Answer to Question 1

ANS: C
Because the weight of the atmosphere retards the escape of vapor molecules, the greater the am-bient pressure, the greater is the boiling point.

Answer to Question 2

ANS: A
A liquid can also change into a gas at temperatures lower than its boiling point through a process called evaporation.
