The PV diagram for cyclic process is a triangle ABC see Fig. drawn in order. The co-ordinates of A, B and Care (4,1), (2,4) and (2,1). The co-ordinates are in order of P and V in which P is N/m^2 and volume is in litre. Calculate the work done during the process from A to B, B to C and C to A. Also calculate the work done in the complete cycle.

1.	The PV diagram for cyclic process is a triangle ABC see Fig. drawn in order. The co-ordinates of A, B and Care (4,1), (2,4) and (2,1). The co-ordinates are in order of P and V in which P is N/m^2 and volume is in litre. Calculate the work done during the process from A to B, B to C and C to A. Also calculate the work done in the complete cycle.
Answer» Solution :WORK done == Area of TRIANGLE `ABC = (1//2) XX 3 xx 10 ^(-3) xx 2 = 3 xx 10 ^(-3) J`
