1.	consider the cyclic process ABCA on a sample of 2.0 mol of an ideal gas as shown in the fig. temperature of the gas at A and B are 300 K and 500 k respectively. A total of 1200 J heat is withdrawn from the sample in the process. Find the work done by the gas in part BC. takeR=8.3 JK^(-1) mol^(-1)
Answer» Solution :`W _(BC) = W _(AB) + W _(n et) = 4 P ( V _(B) - V _(A)) + W _(n et) = 4 R ( 503 - 303) + W _(n et) = 6648 + 2000 = 8648 J`
