In a P-V diagram (for an ideal gas), an isothermal curve will coincide withan adiabatic curve (through a point), when
A. Cp < Cv
B. Cp = Cv
C. Cp > Cv
D. Cp ≥ Cv
Answer: Option B
Solution (By Examveda Team)
The slope of isothermal process in $$p-v$$ plane is \[\frac{{dP}}{{dV}} = \frac{{ - P}}{V}\]The slope of adiabatic process in $$P-V$$ plane is \[\frac{{dP}}{{dV}} = - \gamma \frac{P}{V}\]
\[ \Rightarrow \] Slopes become equal when \[\gamma = 1\]
