Adiabatic free expansion of ideal gas must be
- A Isobaric
- B Isochoric
- C Isothermal
- D Isoentropic
Answer & Solution
Correct Answer
(C) Isothermal
Step-by-step Solution
Detailed explanation
According to first law of thermodynamics \(\begin{aligned} & Q=d U-W \\ & \Rightarrow Q=d U-\left[-P_{\text {external }}\left(V_f-V_i\right)\right] \end{aligned}\) [In Adiabatic Process \(Q=0\), In Free expansion \(P_{\text {extermal }}=0\) ] \(\therefore\) Putting the values,…
