A given mass of gas expands from state A...

A given mass of gas expands from state `A` to state `b` by three paths `1,2`, and `3` as shown in the figure below. If `w_(1),w_(2)` and `w_(3)`, respectively, be the work done by the gas along three paths, then

A

`w_(1) gt w_(2) gt w_(3)`

B

`w_(1) lt w_(2) lt w_(3)`

C

`w_(1) = w_(2) = w_(3)`

D

`w_(1) lt w_(2), w_(1) lt w_(3)`

Text Solution

Verified by Experts

`W_(1) lt W_(2) lt W_(3)`
Work is a path-depends function.
