,Answer:
◉ _____ air holds MORE moisture than cold air. Air is dryer in winter.
Answer: Warm
◉ As the air gets warmer, RELATIVE HUMIDITY is _______.
100% RH in cold climate is DRYER than 50% RH in a warmer
climate.
Answer: Lowered
◉ ____ is the amount of moisture in the air compared to what the air
can hold at that temperature.
RH is the amount of water vapor (individual water molecules) in a
given parcel of air RELATIVE to the # of water molecules that could
be in that particular parcel of air.. without it reaching dew point (
Air is 78% nitrogen molecules, oxygen and others. Molecules aren't
interacting w/ eachother. Space between them. We can put WATER
MOLECULES in that space.
RH = how many water molecules we are putting in the spaces
between the air molecules.
,As air is heated --> molecules move faster --> spread further apart ---
> VOLUME INCREASES. More space for more water molecules.
Answer: Relative Humidity (RH)
