In the adjoining diagram, the p-V graph of an ideal gas is shown. Find out from the graph (i) work done in taking the gas
From the state `AtoB` (ii) Work done in taking the gas from `BtoC` (iii) Work done in a complete cycle. (1 litre`=10^(-3)m^(3)`)

Explanation

(i) `-60xx10^(2)J`
(ii) zero
(iii) `36xx10^(2)J` , i.e., net work is done by the gas
