Which of the following statement is correct regarding \(p-V\) graph?
1. Slope of \(p-V\) graph in an isothermal process is \(-\frac{p}{V}\).
2. Slope of \(p-V\) graph in an adiabatic process is \(-\frac{p}{V}\).
3. Slope of \(p-V\) graph in an isochoric process is \(-\frac{\gamma p}{V}\).
4. Slope of \(p-V\) graph in an isobaric process is zero.
- A 1, 3, 4 are correct
- B 2, 3 are correct
- C 1, 4 are correct
- D 2,3,4 are correct
Answer & Solution
Correct Answer
(C) 1, 4 are correct
Step-by-step Solution
Detailed explanation
(i) and (iv) options are correct. (i) Slope of \(p-V\) graph in an isothermal process is \(-\frac{p}{V}\) this is correct. For isothermal process, slope of \(p-V^{\prime}\) curve \(\frac{d p}{d V}=-\frac{p}{V}\) (ii) Slope of \(p-V\) group in an adiabatic process is…
