What does a vertical line on a p-V diagram represent?.
- A.Isothermal process
- B.Adiabatic process
- C.Constant pressure process
- D.Constant volume process
Model answer
What a good answer should say
- Constant volume process
Explanation
Why this works
A vertical line on a p-V diagram indicates that the volume of the gas remains constant while the pressure changes. This is characteristic of an isochoric process, where no work is done on or by the gas since there is no change in volume.
Understanding this helps in analyzing the energy changes in thermodynamic processes.
