A Carnot engine, having an efficiency of `eta=1//10` as heat engine, is used as a refrigerator. If the work done on the system is 10J, the amount of energy absorbed from the reservoir at lower temperature is

A Carnot engine having an efficiency of eta = (1 / 10) as a heat engine is used as a refrigerators. If the work done on the system is 10 J, what is the amount of energy absorbed from the reservoir at lowest temperature ?

A carnot engine having an efficiency of (1)/(5) is being used as a refrigerator. If the work done on the refrigerator is 8 J, the amount of heat absorbed from the reservoir at lower temperature is:

A carnot engine having an efficiency of 1/4 is being used as a refrigerator. If the work done on the refrigerator is 5 J, the amount of heat absorbed from the reservoir at lower temperature is:

A carnot engine having an efficiency of (1)/(5) is being used as a refrigerator. If the work done on the refrigerator is 8 J, the amount of heat absorbed from the reservoir at lower temperature is:
