Thermodynamics 2 a) An engine receives 680 J of heat from a hot reservoir and gives off 270 J of heat to a cold reservoir. Determine the efficiency of this engine. b) Using a schematic diagram, briefly explain the energy transfer in an air conditioner. c) An ideal gas is compressed at constant pressure to 65% its initial volume. If the pressure of the gas is 1 atm and 820 J of work is done on it, find the initial volume of the gas.
