Water in the air
Terms in this set (26)
Does water exist in the atmosphere in all 3 states of matter?
Liquid water being pushed out in to the atmosphere from plants (evap)
T/F Water vapor may enter the atmosphere from any place on the surface where water exists in any form.
What are the four major sources of water vapor in order?
Oceans, lakes, glaciers, marshes
the change ffrom the invisible water vapor (gas) to the visible water (liquid)
heat energy is removed from the surrounding environment
heat energy is returned to the surrounding environment
a given volume of water will fill the air to capacity AT A GIVEN TEMP, as the temp drops the air will release all excess water vapor will condense into visible water droplets
On the ground
in the air
The temp, to which the air must be cooled, before condensation can begin
In the air
Condensation does not occur unless tiny particles called condensation nuclei are present for the water vapor to condense on
most common condensation nuclei in order
dust, salt, pollen,ice crystals, gas molecules, volcanic ash, smoke particles (solids)
How does salt enter the atmosphere?
from evaporation of ocean water
enters the atmosphere from the incomplete combustion-car and trucks and buses.
Dew and frost
When air is below the dew point by contact (touching) with a cold surface, the water vapor condenses directly on that surface.
greater than 32f
the resulting droplets of water called dew form directly on the cold surface
less than sign 32f
The water vapor sublimates directly into ice crystals known as frost.
Liquid to gas
Gas to liquid
solid to liquid
liquid to solid
solid to gas and vise versa.
