The pressure and volume of a gas are changed along the path ABCA in the graph. The vertical divisions on the graph represent 4.00 105 Pa, and the horizontal divisions represent 5.00 10-3 m3. Determine the work done (including algebraic sign) in each segment of the path.

(a) A to B = 0

(b) B to C

(c) C to A

2. Relevant equations

Area of Triangle=.5lwh

(0th and 1st Laws of Thermodynamics)

3. The attempt at a solution

What exactly am I supposed to figure out, and how am I supposed to go about doing this? I'm thrown off by the graph and what to do with it? What is it saying about the scale? If someone can explain HOW to get the numbers that I need to make the calculations (and why to use them), I can probably work it out (I assume I use the area of a triangle in there somewhere, but perhaps I'm wrong).
