Refer to diagram 2.
A flask contains 78.2 moles of a monatomic ideal gas at pressure 8.33 atm and volume 49 liters. point A on the graph. Now, the gas undergoes a cycle of three steps:
- First there is an isothermal expansion to pressure 1.74 atm (point B on the graph).
- Next, there is an isochoric process in which the pressure is raised to P1 (point C on the graph).
- Finally, there is an isobaric compression back to the original state (point A on the graph).
Find the total work done, in kJ, over the entire cycle (from A back to A).
A positive value means work was done by the gas; a negative value means work is done on the gas. Why is this a poor sort of engine?
Answer :
In question value of P1 is not given but i solved it so i am uploading the answer please put the value of P1 in th equation.
