Aperfect gas is contained in a cylinder of fixed volume and is separated into two sections a and b by a frictionless piston; no heat can pass ugh the piston. section b is maintained at a constant temperature of 300k; that is, all changes in section b are isothermal. there are 2.00 mol of gas molecules in each section and the constant-volume heat capacity of the gas is 20]k mol", which can be assumed to be constant. initially t v, m - t, 300 k, v v 2.00 dm3. energy is then supplied as heat to section a so that the gas in a expands, pushing the piston out and thereby compressing

Hunter is in lab. he clears a spot on his lab bench to start working. he also puts his lab coat and goggles on. he then identifies where all of the safety equipment is. he notices his station is next to the fume hood, which ventilates the chemicals stored there. the noise of the fume hood was bothersome, so hunter turned it off. which could be an error in his set-up? he should not turn off the fume hood.  he should wait to put on his coat until after the directions are given.  he should wait to put on his goggles until after the directions are given.  he should not sit next to the fume hood.
