Sci - Water in Atmos

Includes: Jason-Mission 2 - Fog, Dew, Frost/Water Vapor on Air, and p.28-31notes

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)
