An engine manufacturer makes the claim that the engine they have developed will, on each cycle take 100 J of heat out of boiling water at 100 deg C, do mechanical work of 80J, and exhaust 20 J of heat at 10 deg C. What, if anything, is wrong with this claim? A) An engine would operate by taking in heat at the lower temperature and exhausting heat at the higher temperature, B) There is nothing wrong with this claim because 100J = 20j + 80J, C) The heat exhausted must always be greater than the work done according to the second law of thermodynamics, D) The efficiency of this engine is greater than the ideal Carnot cycle efficiency.
