Q.

P - T curve for a cyclic process is as shown

P - V graph for this process will be:

1  
2  
3  
4  

Ans.

(4)

⇒ Slope of line joining origin to that point ∝1V

As the slope of line OE is greater than the slope of line OC, SO, volume at 'E' is less than that at 'C'.

Therefore, answer is (4).
