As shown in figure three paths through which a gas can be taken from the state A to the state B. Calculate the work done by the gas in each of the three paths.

Explanation

`DeltaW_(ACB)=DeltaW_(AC)+DeltaW_(CB)`
`=0+30xx10^3xx(25-10)xx10^-6`
`=0.4J`
`DeltaW_(AB)=(1)/(2)(10+30)xx10^3xx(25-10)xx10^-6`
`=0.30J`
`DeltaW_(ADB)=DeltaW_(AD)+DeltaW(DB)`
`=10xx10^3xx(25-10)xx10^-6+0`
`=0.15J`
