Diamonds are usually cut with a shape similar to that shown at the right. Kent Affordit is preparing to propose to Amanda Befrendswyth. In an effort to save money, Kent asked the jewleer to remove the bottom portion of the gem. He reasoned that since it won’t be visible, its removal would have little consequence to the appearance. Explain why Kent’s proposal didn’t go so well...

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)
