Part A You decide to use your body as a Camot heat engine. The operating gas is in a tube with one end In your mouth (where the temperature is 37.0 "C) and the other end at the surface of your skin, at 30.0 °C. What is the maximum efficiency of such a heat engine? Would it be a very useful engine? e = 2.26 % Previous Answers v Correct Part B Suppose you want to use this human engine to lift a 2.45 kg box from the floor to a tabletop 1.30 m above the floor. How much must you increase the gravitational potential energy? V = 31.2 J Submit Previous Answers
