n' moles of an ideal gas having molar mass M is made to undergo a cyclic process ABCDA. The cycle has been represented on a pressure (P) density `(rho)`) diagram.
(a) Draw the corresponding P – V diagram
(b) Calculate the work done by the gas in the cycle

Text Solution

Verified by Experts

The correct Answer is:
`(a) `(##IJA_PHY_V02_C04_E01_046_A01##)`
(b) `W=-(nM)/(rho_(1)) (P_(2)-P_(1)) ln ((rho_(2))/(rho_(1)))`
