How is work done calculated in a non-flow process using a p-V diagram?.
- A.By measuring the area under the curve.
- B.By calculating the slope of the curve.
- C.By finding the total pressure.
- D.By determining the change in volume.
Model answer
What a good answer should say
- By measuring the area under the curve.
Explanation
Why this works
