The P-V diagram of a gas undergoing a cyclic process (ABCDA) is shown in the graph, where P is in units of Nm^(-2) and V in cm^(3). Identify the incorrect statement.

1.	The P-V diagram of a gas undergoing a cyclic process (ABCDA) is shown in the graph, where P is in units of Nm^(-2) and V in cm^(3). Identify the incorrect statement.
Answer» 0.4 J of work is done by the gas from A to B 0.2 J of work is done on the gas from C to D. No work is done by the gas from B to C. Work is done by the gas from B to C and on the gas from D to A. Solution :In going from B to C and from D to A, V = CONSTANT. So, `DELTA V = 0. :. W = P Delta V = 0`
