A supplier wants to sell us a device to compress 10kg/min of carbon dioxide isothermally at 31C from 221.5 bar to 369.2 bar. According to the supplier, during operation the device uses 36kJ/min of work and expels an unspecified of heat to the surroundings (at 25C). We need to determine whether we should purchase the device. (a) [40 points ] Determine the amount of heat expelled by the device. (b) [40 points] Determine the entropy change per mole of the carbon dioxide. (c) [20 points] Does the device violate the second law
