Find work done by the gas in the process shown in figure.

A

`(5)/(2) pi atm L`

B

`(5)/(2) atm L`

C

`- (3)/(2) pi atm L`

D

`- (5)/(4) pi atm L`

Text Solution

Verified by Experts

The correct Answer is:
D
d. Area of cycle `= |W|`
`= (pi (4 - 3) (4 - 2))/(2) + (pi (2 - 1) (3 - 2.5))/(2)`
`= (2.5 pi)/(2) = (5 pi)/(4) atm L`
`W = - ((5 pi)/(4)) atm L`
