Assertion: `C_(P)-C_(V)=R` for an ideal gas.
Reason: `((delE)/(delV))_(T)=0` for an ideal gas.

Options

A. If both (`A`) and (`R`) are correct and (`R`) is the correct explanation of (`A`).
B. If both (`A`) and (`R`) are correct, but (`R`) is not the correct explanation of (`A`).
C. If (`A`) is correct, but (`R`) is incorrect.
D. If (`A`) is incorrect, but (`R`) is correct.

Answer

A, B, C, D

Explanation

Both are correct, but reason is not the correct explanation of assertion.
`C_(P)-C_(V)=R`
or `((delH)/(delT))_(P)-((delU)/(delT))_(V)=R`
