A gas undergoes A to B through three different processes 1,2 and 3 as shown in the figure. The heat supplied to the gas is `Q_1`, `Q_2` and `Q_3` respectively, then

A

(a) `Q_1=Q_2=Q_3`

B

(b) `Q_1ltQ_2ltQ_3`

C

(c) `Q_1gtQ_2gtQ_3`

D

(d) `Q_1=Q_3gtQ_2`

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaU` is same p.
`Q=W+DeltaU`
`W_1=+ve`, `W_2=0`
and `W_3=-ve`
