Hot Ice
Latent Heat
Latent heat: the heat required to melt or evaporate a substance
When a substance freezes or condenses, the latent heat is
released back into the environment
As water condenses to form a
cloud, all of the heat that went
into evaporating the water in
the first place is released to
the air.
Clouds warm the air inside the
cloud.
Amount of energy released
equivalent to a small nuke

Specific Heat
The specific heat of a substance is the amount of heat required to
increase the temperature of 1 gram of the substance 1° C
!!! Specific Heat of Water > Specific Heat of Land !!!
Land heats/cools faster than water
