Sci - Water in Atmos
Includes: Jason-Mission 2 - Fog, Dew, Frost/Water Vapor on Air, and p.28-31notes
| Question | Answer |
|---|---|
| phase change | change in a solid, liquid, or gas, to another state |
| melting | change from solid to liquid |
| evaporation | change of liquid to gas |
| sublimation | change of solid to gas w/o the liquid state |
| condensation | change of gas to liquid |
| freezing | change of liquid to solid |
| deposition | change of gas to a solid w/o the liquid state |
| transfer | any gain or loss of heat |
| fog | low-lying stratus clouds; at ground level; formed by condensation |
| dew | water vapor condenses to liquid on objects near ground; ground cold; air temp below dew pt. temp = not enough energy to keep water as vapor |
| frost | water vapor into ice (deposition) on objects near ground |
| humidity | amount of water vapor in air; higher temp = more energy to evap. water and to keep more water as vapor; higher temp = higher humidity possible (depends on water available); ave. humidity = water 2-3% of molecules in air |
| absolute humidity | mass of water vapor per volume of air (g/m cubed) |
| relative humidity | ratio in % that compares water vapor in air to total amount the air could hold at that temp. |
| dew point | temp. at which water vapor loses enough energy to condense (meas. in degrees) |
