Question

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

The gas starts out at point 1 with a volume of ?1=233 cm3, a pressure of ?1=235 kPa, and a temperature of 287 K. The gas is held at a constant volume while it is heated until its temperature reaches 455 K (point 2). The gas is then allowed to expand adiabatically until its pressure is again 235 kPa (point 3). The gas is maintained at this pressure while it is cooled back to its original temperature of 287K (point 1 again).

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

?12=

For the second stage, calculate the heat ?23 transferred to the gas and the work ?23 done by the gas.

?23=

For the third stage, calculate the heat ?31 transferred to the gas and the work ?31 done by the gas.
