Extracted text: What effect does convection have on evaporation if you leave a petri dish of agar in the fume hood instead of uncovered on the bench (both dry air at 293 Kand 1.013 x 10PPA), when you compare mass transfer coefficients (kc fumehood Vs kc room) and kc rfumehood). Water evaporates from the exposed area into the still lab air at a rate of 5.73 x 10-6 mole/s (WA room). In the fume hood, it evaporates into a dry air stream at a rate of 2.29 x 104 mole/s (WA Fumehood).
