SELECTED ANSWER 👀 evaporation
As moisture evaporates from a wet material, the surface of the material becomes
______ because energy is released from the material- - SELECTED ANSWER 👀
cooler
___. occurs when vapor changes to a liquid. occurs as energy is removed - -
SELECTED ANSWER 👀 condensation
____ occurs when a solid changes to a vapor( without going through a liquid
phase.) - - SELECTED ANSWER 👀 sublimation
freeze-drying (sublimation) is typically used with valuable saturated books and
documents. Books and documents saturated with clean water may be restorable
if ___ or ___ as quickly as possible - - SELECTED ANSWER 👀 frozen or dried
,______ is defined as the amount of moisture contained in an air sample as
compared to the maximum amount the air could hold at the temperature- -
SELECTED ANSWER 👀 relative humidity
when the air temperature increases , it can hold ____ water vapor - - SELECTED
ANSWER 👀 more
In the restorative drying industry the weight measurement used to measure
water vapor in air is grains per pound of air, abbreviated as GPP. This is called - -
SELECTED ANSWER 👀 humidity ratio
which of these surface temperatures would prompt the most rapid evaporations?
60 degrees
70 degrees
80 degrees - - SELECTED ANSWER 👀 80
if a material is not drying well what would be the most effective method of
increasing evaporation? - - SELECTED ANSWER 👀 warm the material
one of the most effective methods of drying wet wood under hard surfaces is - -
SELECTED ANSWER 👀 heated airflow.
Use of Psychometrics chart to complete the following calculation
80 F at 60% RH
53 F at 80% RH - - SELECTED ANSWER 👀 91 GPP
, 48 GPP
* which of the two conditions has the lowest vapor pressure?
53 F at 80% RH = 48 GPP
*what is the surface temperature at which condensation would become a risk for
air which is 80 F at 60%
102 F (dew point)
what is the temperature in degrees F if the humidity ratio is 70 GPP and the
relative humidity is 60% - - SELECTED ANSWER 👀 72 F
____ is the temperature at which air becomes saturated with moisture and can
hold no more water vapor - - SELECTED ANSWER 👀 dew point
when air is cooled its capacity for water vapor is reduced, eventually If
temperature is cooled enough, the relative humidity will reach ____% or
saturation. when this occurs the air has reached its ___ point temperature- -
SELECTED ANSWER 👀 100%
dew point
if surfaces are _____ then the dew point of the surrounding air, water will
condense on those surfaces and possibly cause secondary damage. if surfaces are
_____ then the dew point of the surrounding air, evaporation can occur- -
SELECTED ANSWER 👀 cooler
warmer
