A heat engine takes in 2000 J of heat from a high-temperature reservoir and produces 800 J of work. How much heat is rejected to the low-temperature reservoir?
According to the first law of thermodynamics, the heat input to a heat engine is equal to the sum of the work done and the heat rejected. Therefore, the heat rejected to the low-temperature reservoir is 2000 J - 800 J = 1200 J.
