Given below are two statements:
Statement-I: For isothermal irreversible change of an ideal gas, \(q=-w=\mathrm{P}_{\text {ext }}\left(\mathrm{V}_{\text {final }}-\mathrm{V}_{\text {initial }}\right)\)
Statement - II: For adiabatic change, \(\Delta \mathrm{U}=\mathrm{W}_{\text {adiabatic }}\)
The correct answer is
- A Both Statement-I and statement-II are correct
- B Both Statement-I and statement-II are not correct
- C Statement-I is correct but statement-II is not correct
- D Statement-I is not correct but statement-II is correct
Answer & Solution
Correct Answer
(A) Both Statement-I and statement-II are correct
Step-by-step Solution
Detailed explanation
For isothermal process, \(\Delta \mathrm{U}=0\) \(\therefore \mathrm{q}=-\mathrm{w}=\left(-\mathrm{P}_{\text {ext }} \Delta \mathrm{V}\right)=\mathrm{P}_{\text {ext }}\left(\mathrm{V}_{\text {final }}-\mathrm{V}_{\text {initial }}\right)\) for adiabatic process, \(q=0\)…
