Using the data presented in the accompanying pressure-versus-volume graph, estimate the work done (including the algerbraic sign) when the system changes from A to B to C along the path shown.
The work done is the area from change in position and time
The Attempt at a Solution
I counted 5X6 from the initial position to the next for both AB and BC
Given 1000 Pa and .002 m^3
Work = 1000 * .002 *60 = 1200 J
Do I have to include the whole area under the red lines starting from A to C?
