Given T-p curve for three processes. Work done in process 1, 2 and 3 (if initial and final pressure are same for all processes) is `W_(1),W_(2)` and `W_(3)` respectively. Correct order is

Options

A. `W_(1) lt W_(2) gt W_(3)`
B. `W_(1) gt W_(2) gt W_(3) `
C. `W_(1) lt W_(2) lt W_(3)`
D. `W_(1)=W_(2_=W_(3)`

Answer

B

Explanation

Here `TalphaP^(n)` where for , graph-`1` , `ngt1 implies Wgt0 ,` = graph-`2` , `n=1 implies W=0`, graph-`3` `n, lt1 implies Wlt0`
