Exam-style question
Try this first
In a p-V diagram, how would you distinguish between expansion work and compression work?.
Model answer
What a good answer should say
- Expansion work is represented by the area under the curve when the volume increases, while compression work is represented by the area under the curve when the volume decreases.
Explanation
Why this works
This answer effectively distinguishes between the two types of work based on the changes in volume shown in the p-V diagram. This understanding is essential for interpreting thermodynamic processes and calculating work done in engines.
