There are two Carnot engines A and B operating in two different temperature regions. For Engine A the temperatures of the two reservoirs are 150°C and 100°C. For engine B the temperatures of the reservoirs are 350°C and 300°C. Which engine has lesser efficiency?

Three engines operate between reservoirs separated in temperature by 300 K. The reservoir temperatures are as follows: Engine A: Th = 1 000 K, Tc = 700 K; Engine B: Th = 800 K, Tc = 500 K; Engine C: Th = 600 K, Tc = 300 K. Rank the engines in order of theoretically possible efficiency from highest to lowest.

The hot and cold reservoirs of a Carnot engine are 323°C and 64.2°C respectively. The temperature of the hot reservoir is raised by 43°C in order to increase the efficiency of the engine. (a) What is the efficiency after the increase in temperature? % (b) Instead of raising the temperature of the hot reservoir, if the temperature of the cold reservoir is decreased by 43°C, what would be the efficiency of the engine? %
A Carnot engine operates between reservoirs at 400 degrees C and 30 degrees C. (A) Calculate the efficiency of the engine. (B) If the engine does 5.0 J of work per cycle, how much heat per cycle does it absorb from the high-temperature reservoir? (C) How much heat per cycle does it exhaust to the cold-temperature reservoir? (D) What temperatures at the cold reservoir would give the minimum and maximum efficiency?
