It is claimed that, while running through a whole number of cycles, a heat engine takes in 23 kJ of heat, discharges 16 kJ of heat to the environment, and performs 2 kJ of work. What is wrong with the claim?  The work performed equals the difference between the heat output and the heat input. The work performed does not equal the difference between the heat input and the heat output. There is nothing wrong with the claim. The work performed does not equal the difference between the heat output and the heat input. The work performed does not equal the sum of the heat input and the heat output.
