2. True or False: Air is made up of approximately 78% oxygen and 21% nitrogen.

3. True or False: As an air sample is heated, the relative humidity of the air sample goes down.

4. True or False: As an air sample is cooled, the density of the air sample increases.

5. True or False: If you know only the absolute humidity of an air sample, you can also determine the air sample's dew point temperature.

6. True or False: The specific volume and density of an air sample are inversely related to each other.

7. True or False: If an air sample has a relative humidity of 100%, the dry-bulb and wet-bulb temperatures are the same.

8. True or False: One cubic foot of air at standard conditions weighs about 1.2 ounces.

9. True or False: A typical air conditioning system cools and dehumidifies an air stream.

10. True or False: If an air sample is only dehumidified, the relative humidity drops and the dry-bulb temperature increases.
