T-V curve of cyclic process is shown below, number of moles of the gas are n find the total work done during the cycle.

Text Solution

Verified by Experts

Since path AB and CD are isohroic therefore work done is zero during AB and CD process BC and DA are isothermal, therefore
`W_(BC) = nR2T_(0) 1n (V_(C ))/(V_(B)) = 2 nRT_(0) 1n 2`
`W_(DA) = nRT_(0) 1n (V_(A))/(V_(D)) = - nRT_(0) 1n 2`
Total wor done
`W_(BC) + W_(DA) = e nRT_(0) 1n 2 = nRT_(0) 1n 2`
