2. Carpet can be easily damaged while it is wet. If it de- Recommend removal and
laminates the most likely solution is replacement
3. Measures how easily a vapor can pass through a ma- Permeance
terial
4. Carpet seams should only be cut where necessary. To remove carpet padding
What is one necessary reason for cutting seams in
salvable carpet?
5. If drywall ceiling are saturated and sagging, immedi- True
ately remove and dispose of affected ceiling materials
6. When drywall is saturated it gets very soft and it won't False
regain its strength when dry

13. What is the measurable force that vapor creates on the Vapor pressure
things around it
14. What is the temperature at which air reaches 100% Dew point
relative humidity and condensation can occur
15. What is the weight of vapor in dry air called Humidity ratio (grains per
pound)
16. Reducing the amount of water vapor in the air is called Dehumidification
17. The amount of moisture in a sample of air, compared Relative humidity
to the maximum amount that air could have in it, is
called
18. If you heat the air up, but do not add anymore humid- Decrease
ity to it, what will the relative humidity do
19. If you cool the air down, but do not change the amount Increase
of humidity, what will the relative humidity do
20. Vapor pressure, like all other pressure seeks Equilibrium
21. On a project with 50 degree air inside, what type of Desiccant
dehumidifier could work?
22. In order to use LGR dehumidification on a project True
that is 50 degrees inside, supplemental heaters will be
needed
