The pressure and volume of a gas are changed along a path ABCA in the figure. The vertical divisions on the graph represent 2.5 105 Pa, and the horizontal divisions represent 1.0 10-3 m3. Determine the work done (including algebraic sign) in each segment of the path.

a. A to b
b. B to C
c. c to A

itis in a shape of a right-angled triangle turn upside down

i solved it. Thanks. To find work W=PV ie Multiply the P by V given. count the squares beneathe the line and multiply by the work. If it's a vertical line, it has no squares beneathe, thus, it's 0.
