water Molecules combine with liquid
condensation
-water vapor pressure
-relative humidity
-Dew Point Pressure
condensation equilibrium
evaporation
If saturation vapor pressure is 17mb at 15 degrees celsius, about what is it at 5 degrees celsius?
9
Decrease in Temperature
---> eventually reach _______
--->__________
dew point, saturation
Evaporation
small reservoir, but with lots of water movement
atmosphere
ice to water vapor
-without becoming a liquid
Sublimation
An increase in temperature leads to....
an increase of saturation vapor pressure= more water vapor can exist
Relative Humidity=
%
True or False: Nitrogen Pressure is less than water vapor pressure
False
Water vapor in the atmosphere
Atmospheric Pressure
Water vapor to ice
-without becoming a liquid
Deposition
Saturation vapor pressure doubles for every 10 C rise in temp
Relative Humidity tells....
how close water vapor pressure is to saturation
mb=milibars
evaporation and condensation rates are equal, maximum amount of water vapor present
saturation
Saturation vapor pressure depends on....
temperature
Rule of Thumb ---> 10 C
18 F
temperature you must cool air so that the air is saturated with water vapor
dew point
Pressure contributed by water vapor
Water Vapor Pressure
Maximum amount of water vapor that can exist
Saturation Vapor Pressure
What happens to additional water vapor under saturation vapor pressure?
it condenses
10 C(50 F)---> 20 C =
68 F
Dew Point Units
C or F
