An ideal gas undergoes a cyclic transformation starting from the point A and coming back to the same point by tracing the path A → B → C → A as shown in the diagram. The total work done in the process is _____ J .

Correct answer

0

Step-by-step solution

Work done is given by area enclosed in the P vs V cyclic graph or V vs P cyclic graph Sign of work is positive for clockwise cyclic process for V vs P graph. Work done in cyclic process = area inside the figure W = 1 2 × ( 30 - 10 ) × ( 30 - 10 ) = 200 kPa - dm 3 = 200 × 1000 Pa - L = 2 L - bar = 200 J
