During an adiabatic expansion, a gas obeys `VT^(3) =` constant. The gas must be

A

Monoatomic

B

Diatomic

C

Polyatomic

D

Any of above

Text Solution

Verified by Experts

`VT^(3) =` constant,
Also `V^(gamma-1)T =` constant for adiabatic expansion.
`V.T^((1)/(gamma-1)) =` constant or `(1)/(gamma -1) = 3`
`gamma = (4)/(3)`, i.e., poyatomic gas.
