A refrigerator has a coefficient of performance of 1.15, and it extracts 7.95 J of heat from the cold reservoir during each cycle. (a) How much work is done on the gas in each cycle? (b) How much heat is exhausted into the hot reservoir in each cycle? I've seen a similar question, but I still don't understand how to solve. Can I get help please, step by step would be kind.
An ideal refrigerator extracts 410 joules of heat from a reservoir at 290 K and rejects heat to a reservoir at 488 K. What is the ideal coefficient of performance and how much work is done in each cycle?
An ideal refrigerator extracts 420 joules of heat from a reservoir at 280 K and rejects heat to a reservoir at 498 K. What is the ideal coefficient of performance and how much work is done in each cycle? COP = Number Work = Number Joules
SP3. A Carnot engine operating in reverse as a heat pump moves heat from a cold reservoir at 7°C to a warmer one at 22°C. a) What is the efficiency of a Carnot engine operating between these two temperatures? b) If the Carnot heat pump releases 250 J of heat into the higher-temperature reservoir e co in each cycle, how much work must be provided in each cycle? c) How much heat is removed from the 7°C reservoir in each...

A Carnot engine extracts 910J from a 550K reservoir during each cycle and rejects 500J to a cooler reservoir. It operates at 22 cycles per second. Find the work done during each cycle. Find its efficiency. Find the temperature of the cool reservoir. Find its mechanical power output.
(a) During each cycle, a Carnot engine absorbs 772 J as heat from a high-temperature reservoir at 388 K, with the low-temperature reservoir at 287 K. How much work is done per cycle? (b) The engine is then made to work in reverse to function as a Carnot refrigerator between those same two reservoirs. During each cycle, how much work is required to remove 1206 J as heat from the low-temperature reservoir? () Numbel 200.9590 UnitsT j UnitsT j (b)...
A refrigerator is constructed with a Carnot engine. Draw a diagram of the Carnot cycle in a P-V diagram, label the components, and then detail the processes that occur (I short phrase each is all that is necessary). Draw a diagram of the Carnot cycle in a H-S diagram, and label it to match (a) Note: His enthalpy and S is entropy. Water is brought to 0 °C in the refrigerator with the heat being discharged into a reservoir at...
