JEE Mains · Chemistry · STD 11 - 5. Thermodynamics and thermochemistry
Five moles of an ideal gas at \(1\) bar and \(298\, K\) is expanded into vacuum to double the volume. The work done is :-
- A \(C _{ V }\left( T _{2}- T _{1}\right)\)
- B \(- RT \ln V _{2} / V _{1}\)
- C \(- RT \left( V _{2}- V _{1}\right)\)
- D zero
Answer & Solution
Correct Answer
(D) zero
Step-by-step Solution
Detailed explanation
As the expansion is done in vaccum that is in absence of \(p _{\text {ext }}\) so \(W=\) zero
