ACTUAL QUESTIONS & VERIFIED ANSWERS
(GRADED A+)
evaporation will increase when - correct-answer-wet materials are made warmer
when drier air is used
air is moved more rapidly across the wet surface
after excess water has been extracted the time needed to dry wet materials is
determined by the - correct-answer-rate of evaporation
as the water has been extracted the time needed to dry wet material is
determined by the - correct-answer-rate of evaporation
As the water is rapidly evaporated, the water vapor is removed by
________________ or ___________. - correct-answer-dehumidification or
ventilation
,2|Page
_____ occurs when liquid changes to a vapor. occurs as energy is increased -
correct-answer-evaporation
As moisture evaporates from a wet material, the surface of the material becomes
______ because energy is released from the material. - correct-answer-cooler
___. occurs when vapor changes to a liquid. occurs as energy is removed - correct-
answer-condensation
____ occurs when a solid changes to a vapor( without going through a liquid
phase.) - correct-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 - correct-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. -

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 - correct-
answer-humidity ratio
