Question

how much work must be expended to cool this body from room temperature (300K) to 0.5 k, using the ambient atmosphere as the hot Reservoir?

4.6-6. One mole of a monatomic ideal gas is allowed to expand isothermally from an initial volume of 10 liters to a final volume of 15 liters, the temperature being maintained at 400 K. The work delivered is used to drive a thermodynamic refrigerator operating between reservoirs of temperatures 200 and 300 K. What is the maximum amount of heat withdrawn from the low-temperaturc reservoir?

Explanation / Answer

The problem is missing the context of the body for which work to be find it should clear to determine what type and nature of body to describe accurate answer.
