A heat engine using a monatomic gas follows the cycle shown in the ??pV diagram.

The gas starts out at point 1 with a volume of ?1=318 cm3,V1=318 cm3, a pressure of ?1=235 kPa,p1=235 kPa, and a temperature of 287 K.287 K. The gas is held at a constant volume while it is heated until its temperature reaches 455 K455 K (point 2). The gas is then allowed to expand adiabatically until its pressure is again 235 kPa235 kPa (point 3). The gas is maintained at this pressure while it is cooled back to its original temperature of 287 K287 K (point 1 again).

For the first stage of this process, calculate in joules the heat ?12Q12 transferred to the gas and the work ?12W12 done by the gas.

In an engine cycle like the one shown in Figure
In an engine cycle like the one shown in Figure    heat is added over a range of temperatures. Explain why even if it were run reversibly, its efficiency would be less than the Carnot limit defined by the high- and low-temperature set points and shown in the figure ( ηC = T4-T2)/T4. Is this in itself a disadvantage of such a cycle?
