A system changes from the state (P(1),V(...

A system changes from the state `(P_(1),V_(1))` to `(P_(2)V_(2))` as shwon in the diagram. The workdone by the system is

A

`7xx10^(5)` Joule

B

`12xx10^(5)` Joule

C

`25xx10^(5)` Joule

D

`6xx10^(5)` Joule

Text Solution

Verified by Experts

The correct Answer is:
B
Work done = Area under the curve and the V-axis
or Area of the trapezium (ABCD)
`=1/2[1xx10^(5)+5xx10^(5)]xx[5-1]`
`=3xx10^(5)xx4=12xx10^(5)J`
