Answers |Latest Version |Already Graded A+
Psychrometry ✔Correct Answer-Study of the relationship between air, humidity, and temperature
and their effects on materials and comfort levels
Evaporation ✔Correct Answer-Process of changing a liquid to a vapor
Dehumidification ✔Correct Answer-Reducing moisture content in the air
Dry Bulb Temperature ✔Correct Answer-Temperature degree registered by a thermometer

Percent RH
Saturation Point ✔Correct Answer-Point at which air or materials can absorb no more moisture,
drying stops, and air temperature reached dew point
Condensation ✔Correct Answer-Conversion of water from vapor state back to liquid state
Relative Humidity (RH) ✔Correct Answer-The amount of moisture in a given volume of air,
expressed as a percentage, at a given temperature
Infiltration ✔Correct Answer-Migration of air into an area from an outside area due to high VP
differential
Balanced Drying ✔Correct Answer-Ideal drying situation in which the rate of evaporation is equal
to or slightly less than the rate of dehumidification or ventilation

Hygroscopic ✔Correct Answer-Material that readily absorbs and retains moisture or water vapor
from air in an attempt to reach equilibrium
Moisture Content (MC) ✔Correct Answer-Weight or percentage of moisture in materials, as
compared to the weight of oven dried , like material
Permeance ✔Correct Answer-A measure of water flow through materials of specific thickness
Moisture Gradient ✔Correct Answer-Different levels of moisture content within a wood material
Vapor Pressure ✔Correct Answer-Pressure on surfaces exerted by substances in a gaseous state
directly related to dehumidification
