Assertion : The ratio `C_(P)// C_(upsilon)` for a diatomic gas is more

1.	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.
Answer» Correct Answer - 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")`
