A constant amount of an ideal gas undergoes the cyclic process ABCA in the PV diagram shown below The path BC is an isothermal. The work done by the gas during one complete cycle, beginning and ending at A, is nearly-

Step-by-step solution

array l W _ C A =0 Process BC T = Constant P _ C V _ C = P _ B V _ B 500 2=200 V _ B V _ B =5 ~m ³ ~W _ A B =200 [ ~V _ B - V _ A ]=200[5-2] =600 ~W _ B C > W _ A B array Net work done is - ve array l W _ B C < 1200 KJ Total W < -600 KJ array
