Assertion : The ratio C(P)// C(upsilon) ...

Assertion : The ratio `C_(P)// C_(upsilon)` for a diatomic gas is more than that for a monoatomic gas.
Reason : The moleculess of a monoatomic gas have more degrees of freedom than those of a diatomic gas.

A

If both assertion and reason are true and reason is the correct explanation os assertion.

B

If both assertion and reason are true but reason is not be correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
For a monatomic gas, number of degree of freedom, n = 3, and for a diatomic gas, n= 5.
As, `(C_(P))/(C_(V))=gamma=1+2/n,`
For monatomic gas, `(C_(P))/(C_(V))=5/3=1.67and `
For diatomic gas, `(C_(P))/(C_(V))=7/5=1.4`
`((C_(P))/(C_(V)))_("monatomic")gt((C_(P))/C_(V))_("diatomic")`
