The efficiency of a Carnot cycle is Te ec =1- Th (a) If an engine operating between heat reservoirs at 293K and 473K extracts 1000 J per cycle from the hot reservoir, what is the maximum possible work that engine can do per cycle? (b) For this maximum work, how much heat is exhausted to the cold reservoir per cycle?

An engine absorbs 1.71 kJ from a hot reservoir at 277°C and expels 1.22 kJ to a cold reservoir at 27°C in each cycle. (a) What is the engine's efficiency? %(b) How much work is done by the engine in each cycle? J(c) What is the power output of the engine if each cycle lasts 0.303 s?

A refrigerator has a coefficient of performance of 2.10. Ineach cycle it absorbs 3.10 * 104 J of heat from the cold reservoir. (a)How much mechanical energy is required each cycle to operate the refrigerator?(b) During each cycle, how much heat is discarded to thehigh-temperature reservoir?

An engine operating between heat reservoirs at 20 °C and 200 °C extracts 1000 J per cycle from the hot reservoir. (a) What is the maximum possible work that engine can do per cycle? (b) For this maximum work, how much heat is exhausted to the cold reservoir per cycle?

A Carnot engine operates with an efficiency of 25.0% when the temperature of its cold reservoir is 277K. Assuming that the temperature of the hot resevoir remains the same,what must be the tempature of the cold resevoir in order to icnrease the efficiency to 32.0%?

A heat engine operates in a Carnot cycle between 80.0°C and 350°C. It absorbs 21000 J of energy per cycle from the hot reservoir. The duration of each cycle is 1.00 s. (a) What is the mechanical power output of this engine? (b) How much energy does it expel in each cycle by heat?

A Carnot engine operates between a hot reservoir at 362.0 K and a cold reservoir at 312.0 K. If it absorbs 525.0 J of heat per cycle at the hot reservoir, how much work per cycle does it deliver?   If the same engine, working in reverse, functions as a refrigerator between the same two reservoirs, how much work per cycle must be supplied to remove 985.0 J of heat from the cold reservoir?         Needs complete solution with @/100 % accuracy.
