Me! one airline limits the size of carry-on luggage to a volume of 40,000 cm^3. a passenger has a carry-on that has an area of 1,960 cm^2 and is 23 cm high. is the passenger's luggage ok to carry onto the airplane? show your work.

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
