The ratio of the slopes of isothermal and adiabatic curves is
- A 1
- B \(\gamma\)
- C \(\frac{1}{\gamma}\)
- D \(\frac{3}{2}\)
Answer & Solution
Correct Answer
(C) \(\frac{1}{\gamma}\)
Step-by-step Solution
Detailed explanation
For an isothermal change, \(p V=K\) Differentiating both side, we get \(p \cdot d V+V d p=0 \Rightarrow V d p=-p d V\) \(\therefore\) Slope of an isothermal curve \(\left(\frac{d p}{d V}\right)_{\text {iso }}=-\frac{p}{V}\) For an adiabatic change, \(p V^\gamma=K^{\prime}\)…
