Question

Map Sapling Learning A pressure versus volume (p) diagram is shown in the figure below for a system. The arrows of the curve indicate the direction of the process and the points of interest are labelled. Calculate the amount of work done on the system from 0 2 and then for the entire curve 0 5.The values for the points in the diagram are Pressure (Pa) Volume (m3) Vo 25.0 po E 1.00 x 104 V1 2214 P1 1.00 104 p2 5.55 x 103 V2 E 17.6 V3 13.9 2.50 x 103 V4 13.9 V5 8.19 p5 1.00 x 103 Number 4.45 x 10 J 02 V (cubic m p (Pa) Number Incorrect Ws l 1.12 x 105 J

Explanation / Answer

work W02 = area under curve from 0 to 2

area =1/2* ( 5.55*10^3 + 1*10^ 4 ) * ( 17.6 -25 ) = - 57353 J

work from 0 to 5 same concept here

area = 1/2* ( 1*10^4 + 1*10^3 ) *( 8.19- 25) = -92455 J
