PY
As the air gets warmer, RELATIVE HUMIDITY is _______.
100% RH in cold climate is DRYER than 50% RH in a warmer climate. - Correct
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. - Correct Answer > Relative
Humidity (RH)
D
O
Water that originates from a sanatary water source and does not pose substantial
risk.
N

T
Examples broken water lines, tub or sink overflows with no contaminants,
appliance malfunctions involving water supply lines, rainwater - Correct Answer >
C
Category 1 Water
O
PY
1st indicator that it went from category 1 to 2 --> ___ - Correct Answer > odor
Water that has a significant degree of chemical, biological and/or physical
containment.
Aquarium leaks, waterbed leaks, toilet bowl overflows (that contain urine),
dishwasher or clothes washer discharge, and water that enters the structure from
hydrostatic pressure.
, Has the potential to cause sickness or discomfort and should NOT be allowed to
dwell in a structure for an extended period of time. - Correct Answer > Category 2
Water
Water that contains grossly contaminated water and can cause harmful reactions to
humans. Carries PATHOGENIC AGENTS
Examples sewage, all forms of flooding seawater, water from river, etc. - Correct
Answer > Category 3 Water
D
- Correct Answer > Special Situations
O
N
Originates from a sanitary water source. - Correct Answer > Category 1

Least amount of water, absorption and evaporation load (less than 5% porous
materials wet compared to SF of wet walls, floors and ceilings). - Correct Answer >
Class 1
Large amount of water, absorption and evaporation load (5%-40% porous materials
wet compared to SF of wet walls, floors and ceilings). - Correct Answer > Class 2
