Answer to Question 1

ANS: C
The increased temperature will increase the kinetic activity of the molecules which make up the gas. Charles law states that pressure and temperature are directly proportional. An increase in temperature will increase the pressure.

Answer to Question 2

ANS: B
Either decreasing the temperature or increasing the atmospheric pressure will decrease the evapo-ration rate.
