Question
1. Consider the information in the chart below.
Location
A
B
C
Mixing ratio (g/kg)
6 g/kg
6 g/kg
7 g/kg
Saturation mixing ratio (g/kg)
6 g/kg
12 g/kg
10 g/kg
Relative Humidity (%)
(6/6)*100 = 100
(6/12)*100= 50
(7/10)*100= 70
e. Which location has the highest RELATIVE moisture content? Explain how you determined this.
f. What would you have to do to r at location C to make the air saturated? How could this be done?
g. What would you have to do to rs at location C to make the air saturated? How could this be done?
h. If the temperature cooled at location A, what would happen to its rs?
i. How would this affect r at A? What would happen to the extra water vapor?
2. If the saturation mixing ratio is 8 g/kg and the RH is 25%, what is the mixing ratio?
3. If the relative humidity is 50% and the mixing ratio is 10 g/kg, what is the saturation mixing ratio?
4. Which of the following indicates a decrease in air’s capacity for water vapor?
A. A decrease in mixing ratio
B. A decrease in saturation mixing ratio
C. A decrease in relative humidity
D. A decrease in dewpoint temperature
5. At 10ºC, the atmosphere is saturated with water vapor. If the air temperature increases to 15ºC with no addition or removal of water vapor, one may conclude that the dew point is about:
A. 5ºC.
B. 10ºC.
C. 15ºC.
D. 25ºC.

Explanation / Answer
e. Which location has the highest RELATIVE moisture content? Explain how you determined this?
Answer: Location A
Location A the relative humidity is 100% that is the air has almost all water vapour that it can contain.
f. What would you have to do to r at location C to make the air saturated? How could this be done?
Answer: Increase the mixing ratio to 10 g/kg
By increasing the mixing ratio we will make it a saturation ratio so that the air will be saturated at location C
