Answers
1. Water exists in which forms in the atmosphere? solid, liquid, gas
2. The hydrogen atoms in a water molecule are arranged Asymmetrically
.
3. Water molecules in the air tend to have energy Higher
levels compared to liquid water molecules.
4. What is the primary result of a decrease in energy, An increase in condensa-
such as cooling, on the molecules moving between tion
the liquid and vapor states?
5. In how many different forms does water exist in the 3
atmosphere?
6. The two atoms in a water molecule are arranged Hydrogen
asymmetrically
7. The amount of water vapor in the atmosphere is called Humidity
8. T or F False
Liquid water molecules have more energy, in general,
than molecules of water vapor.
9. Absolute humidity is a measure of how much water grams
vapor is in a given volume of air and is measured in
per cubic meter
10. What is the primary result of an increase in energy, An increase in evaporation
such as heating, on the molecules moving between
the liquid and vapor states?
11. What correctly describes vapor pressure? - Increases with increas-
ing number of water mol-

ecules
- Is symbolized by e
- Is represented in mil-
libars
12. Which of the following two describe the movement of - Deposition
water molecules between a solid and a vapor? - Sublimation
13. Water-vapor is the maximum amount of water air Capacity
can hold.
14. Humidity is the term used to describe . The amount of water va-
por in the air
15. What describes saturated air conditions? - The weather is likely
cloudy and/or foggy.
- The air contains as much
water vapor as it is able to
hold.
16. T or F True
Absolute humidity changes as air expands or con-
tracts in the atmosphere.
17. humidity is usually represented by a percentage Relative
and is the ratio of how much water vapor is in the air
relative to the maximum amount of water vapor that
air can hold.
18. The amount of atmospheric pressure contributed by Vapor
the weight of water vapor in the atmosphere is known
as pressure.
19. 10 g/kg

Answers
Which of the following is a measure of specific humid-
ity?
20. The maximum amount of water vapor that air can Water vapor capacity
hold is called .
21. What best describes unsaturated air conditions? - The air contains less wa-
ter vapor than it is able to
hold.
- The weather is likely fair.
22. Specific humidity will only change if is added or Water Vapor
subtracted through the processes of evaporation or
condensation.
23. What describes relative humidity? The ratio of the amount of
water vapor in the atmos-
phere compared to the
water-vapor capacity
24. T or F True
The primary factor controlling global patterns of spe-
cific humidity is latitude.
25. The mass of water vapor in a body of air compared to Specific
the total mass of that air is humidity.
26. Ice cover and cold temperatures in latitudes result High
in low specific humidities at the poles.
27. Tropics Highest humidity
year-round
28. Poles
