What does a vertical line on a p-V diagram represent?.
- A.Constant pressure process
- B.Constant volume process
- C.Isothermal process
- D.Adiabatic process
Model answer
What a good answer should say
- Constant volume process
Explanation
Why this works
A vertical line on a p-V diagram represents a constant volume process. In this scenario, the volume does not change while the pressure may vary, indicating that the gas is undergoing a process at fixed volume.
This is important for understanding how gases behave under different thermodynamic conditions.
