Water in the Atmosphere

1. The process by which a solid changes directly into a gas is called:

a. evaporation b. condensation c. sublimation d. precipitation

2. ost water enters the atmosphere by the process of:

a. evaporation b. sublimation c. condensation d. precipitation

3 Energy stored in molecules is called:

a. latent heat b. humidity c. saturated d. psychrometer

4 The amount of water vapor in the atmosphere is known as:

a. humidity b. psychrometer c. wet bulb d. dry bulb

5 A comparison of the mass of water vapor in the air with the mass of water

vapor that the air can hold when it is saturated is:

a. humidity b. relative humidity c. condensation d. evaporation

6 The instrument used to measure relative humidity:

a. thermometer b. wind vane c. barometer d. psychrometer

7-8 Using the relative humidity chart (pg 481), answer the following questions about the use of a psychrometer.

7. If the dry bulb temperature is 20 degrees C and the wet bulb temperature is 14

degrees C, what is the relative humidity?

a. 34% b. 51% c. 62% d. 78%

8. If the dry bulb temperature is 20 degrees C and the relative humidity is 66%,

what should the wet bulb temperature be?

a. 14 b. 16 c. 18 d. 22

9. The temperature in each of two rooms is 30 degrees C. The relative humidity in the

first room is 80% and the relative humidity in the second room is 70%. The air

conditioning is turned on in each of the rooms and the temperature begins to

cool at an equal rate in both rooms. Which room should show condensation on its

walls first?

a. room one b. room two c. they should show condensation at the same time

d. condensation will never occur in either room

11. Which is the correct sequence showing the changes in phases of water from...
