Air at 50.0% relative humidity is cooled isobarically at 1 atm absolute from 70.0°c to 35.0°c.

a. estimate the dew point and the degrees of superheat of the air at 70.0°c. dew point: °c degrees of superheat: °c

b. how much water condenses (mol) per cubic meter of feed gas? (see example 6.3–2) mol

c. suppose a sample of the 70.0°c air is put in a closed variable-volume chamber containing a mirror and the pressure is raised at constant temperature until a mist forms on the mirror. at what pressure (atm) would the mist form? (assume ideal gas behavior.) atm
