`C_(p)//C_(v)` ratio for noble gases is ________.

A

1.33

B

1.66

C

2.13

D

1.99.

Text Solution

Verified by Experts

The correct Answer is:
B
Inert gases exist as monoatomic molecules. For these,
`C_(p) = (5)/(2) R`
`C_(upsilon) = (3)/(2) R`
`gamma = (C_(p))/(C_(upsilon)) = ((5)/(2)R)/((3)/(2)R) = 1.66`
