An ideal gas heat engine is operating between 227°C and 127°C. It absorbs 104 J of heat at the higher temperature. The amount of heat converted into work is?

An ideal gas heat engine is operating between 227°C and 127°C. It absorbs 104 J of heat at the higher temperature. The amount of heat converted into work is? Correct Answer 2000 J

Ƞ=1-T2/T1 = 1-(273+127)/(273+227)=1-400/500=1/5 W=ȠQ1=1/5×104=2000J.

Two refrigerators M and N operate in series. The refrigerator M absorbs energy at the rate of 1 kW from a body at temperature 400 K and rejects energy as heat to a body at a temperature T. The refrigerator N absorbs the same quantity of energy which is rejected by the refrigerator N from the body at temperature T, and rejects energy as heat to a body at temperature 800 K. If both the refrigerators have the same C.O.P., what is the value temperature T?
