In a question, an engine is advertised as being able to do 4000 J of Work for an output of 6000 J of heat at 500 K. Determine if the seller is telling the truth. (Assume Tc = 300K) Yes! The seller is telling the truth because the efficiency of the engine is higher than the efficiency of Carnot engine. No! It's a scam. The seller is not telling the truth because the efficiency of the engine is always lower than the efficiency of Carnot engine.
