C(P) -C(V) for an ideal gas is………….. ....

`C_(P) -C_(V)` for an ideal gas is………….. .

A

`R^(2)`

B

`sqrt(R )`

C

`R`

D

`R//2`

Text Solution

Verified by Experts

The correct Answer is:
C
For an ideal gas,
`Delta H = Delta U + Delta (pv)`
`=Delta U + Delta (nRT)`
`= Delta U + nR Delta T`
`:. Delta H = Delta U + nR Delta T`
`C_(P) Delta T = C_(V) Delta T + nR Delta T`
`C_(P) = C_(V) + nR`
`C_(P) - C_(V) = nR`
