Freezing and condensation
Melting and evaporation (vaporization)
The energy gained by the sink
Small specific heat
Large specific heat
Liquid water
Terrestrial radiation (infrared)
It has a smaller specific heat
Vapor (gas)
Temperature (and mass)
Radiative balance
Longer (IR is longer than visible light)
Electromagnetic radiation (waves)
Temperature difference between them
Visible light
Absolute zero
Infrared radiation
Dark and rough
Smooth and light in color
Specific heat
