Graded 100% Verifid)
1. Vinyl wall covering affects drying process because it is a vapor retarder: True
2. Carpet can be easily damaged while it is wet. If it delaminates the most likely
solution is: Recommend removal and replacement
3. Measures how easily a vapor can pass through a material: Permeance
4. Carpet seams should only be cut where necessary. What is one necessary reason
for cutting seams in salvable carpet?: To remove carpet padding
5. If drywall ceiling are saturated and sagging, immediately remove and dispose of
affected ceiling materials: True
6. When drywall is saturated it gets very soft and it won't regain its strength when
dry: False
7. Which subfloor material is damaged the least when it gets wet: Plywood
8. To dry the subfloor underneath vinyl flooring, remove the vinyl: True
9. When particle board gets wet what should you do with it: Dispose of it
10. Wet concrete can be dried by applying heat energy: True
11. Drying a wet wall cavity by injecting air into it speeds: Evaporation
12. If the dew point changes, what 2 other humidity measurements change with it:
Vapor pressure and humidity ratio
13. What is the measurable force that vapor creates on the things around it: Vapor
pressure
14. What is the temperature at which air reaches 100% relative humidity and
condensation can occur: Dew point
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 to the maximum amount
that air could have in it, is called: Relative humidity
18. If you heat the air up, but do not add anymore humidity to it, what will the
relative humidity do: Decrease
19. If you cool the air down, but do not change the amount of humidity, what will
the relative humidity do: Increase
20. Vapor pressure, like all other pressure seeks: Equilibrium
21. On a project with 50 degree air inside, what type of dehumidifier could work?:
Desiccant
22. In order to use LGR dehumidification on a project that is 50 degrees inside,
supplemental heaters will be needed: True
1/3
