Exam-style question
Try this first
Describe the process of a heat engine cycle using a p-V diagram. What key features should be included in your description?.
Model answer
What a good answer should say
- A heat engine cycle on a p-V diagram typically includes four key processes: isothermal expansion, adiabatic expansion, isothermal compression, and adiabatic compression.
- Each process corresponds to changes in pressure and volume, illustrating how the engine converts heat energy into work.
Explanation
Why this works
This question tests the understanding of the heat engine cycle and its representation on a p-V diagram. A strong answer demonstrates knowledge of the thermodynamic processes involved and their graphical representation.
