## Homework Statement

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.

## Homework Equations

The work done is the area from change in position and time

Work= PV

## 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?
