Question

can someone help me answer, what is the maximum amount of heat withdrawal from the low temperature 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refrigerator operating between reservoirs of temperatures 200 and 300 K. What is the maximum amount of heat withdrawn from the low-temperaturc reservoir?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

W = nRT ln ( V2/V1) = (1 mole) ( 400 K) )(0.0821 ) ln (1.5) = 13.315 J

200/ ( 300-200) =Q2/ 13.315

Q2=26.63 J
