Question: The efficiency of a particular Carnot engine is 0.280. (a) If the high-temperature reservoir is at a temperature of 565 K, what is the temperature

The efficiency of a particular Carnot engine is 0.280.

(a) If the high-temperature reservoir is at a temperature of 565 K, what is the temperature of the low-temperature reservoir?

(b) To increase the efficiency of this engine to 40.0%, must the temperature of the low-temperature reservoir be increased or decreased? Explain.

(c) Find the temperature of the low-temperature reservoir that gives an efficiency of 0.400.
