7. Mass of water vapor/volume of air
Units: grams/cubic meter
Maximum potential absolute humidity related
to temperature
Temperature increase = increase in potential

9. Mass of water vapor per mass of air
Grams of water vapor/kilograms of air
10. The portion of air pressure that comes from
water vapor
Units: same as air pressure (millibars)
Saturation vapor pressure = maximum
possible
Above saturation condensation
14. 1. Add more moisture and lower
temperature
2. Remove water vapor and lower
temperature
3. Add more moisture and raise temp
4. Remove water vapor and raise temp
15. 1. Relative humidity will increase
2. Relative humidity will stay same
3. Relative humidity will decrease
17. As air cools, maximum water vapor can be
reached.
Dew Pt temperature = temp. at which this
