An ideal gas is taken through a Carnot cycle. The
isothermal expansion occurs at 250°C, and the isothermal
compression takes place at 50.0°C. The gas takes in 1 200 J
of energy from the hot reservoir during the isothermal
expansion. Find (a) the energy expelled to the cold reservoir
in each cycle and (b) the net work done by the gas in
The Attempt at a Solution
Qh-W=Qc (absolute values)
e(Carnot)=(523-323)/523= 61.9 %
(corrected my typo from before)
Therefore Qc= .381(1200J)=457J
and W = 1200-457=743J
Not the correct answer. Qc = 741 according to the solutions manual.
