Work done = press x vol change

Work done(J) = 200,000 Pa x 100 x10-6 m3 = 20 J

Work done = press x vol change

Work done(J) = 200,000 Pa x 100 x10-6 m3 = 20 J

100,000 x 250 x10 - 6

Work done = press x vol change

Work done(J) = 200,000 Pa x 100 x10-6 m3 = 20 J

100,000 x 250 x10 - 6

= 25 J

Work done = press x vol change

Work done(J) = 200,000 Pa x 100 x10-6 m3 = 20 J

100,000 x 250 x10 - 6

= 25 J

Work done = press x vol change

Work done(J) = 200,000 Pa x 100 x10-6 m3 = 20 J

= 12.5 J

Work done = press x vol change

Work done(J) = 200,000 Pa x 100 x10-6 m3 = 20 J

Work done(J) = area under graph = 37.5 J
