For a gas the value of (R)/(C(v)) = 0 . ...

For a gas the value of `(R)/(C_(v))` = 0 . 4 so the gas is
(R-universal gas constant)

A

monoatomic

B

diatomic

C

triatomic

D

polyatomic

Text Solution

Verified by Experts

The correct Answer is:
B
Given , for a gas the value of `(R)/(C_(v)) = 0 . 4`
We know that the relation between `gamma`, R and `C_(v)` is
`rArr gamma - 1= (R)/(C_(v)) or gamma - 1 = 0 . 4`
`rArr gamma = 1.4` which is for a diatomic gas .
