C_(p)-C_(v)=R//J for one mole of the gas. If we consider n moles of the gas, the formula becomes:

Answer»

<P>`C_(p)-C_(v)=(R )/(J)`
`C_(p)-C_(v)=n.R//J`
`C_( r)-C_(v)=(R )/(NJ)`
None of the above.

Solution :`C_(p)-C_(v)=(R )/(J)` Here R is gas constant for 1 mole of the gas.
For n moles of the gas each terms on L.H.S and the term on R.H.S. is MULTIPLIED by n and HENCE even for n moles of gas the relation remains the same.
Thus, correct choice is (a).
