Question

Quizplus · Accepted Answer

The lack of visible condensate in the tubing indicates that the delivered gas is completely saturated with water vapor, meaning that the relative humidity is at 100%. Therefore, the answer is D, less than 100%. The other options are not correct as they suggest lower levels of humidity than what is indicated by the absence of visible condensate.
