Question

If for a gas, (R/CV)=0.67, this gas is made up of molecules which are (A) diatomic (B) mixture of diatomic and polyatomic molecules (C) monoatomic (D) polyatomic

Tardigrade Admin · Accepted Answer

Since (R/CV)=0.67 ⇒ (CP-CV/CV)=0.67 ⇒ &gamma; =1.67= (5/3) Hence gas is monoatomic.

Q. If for a gas, $\frac{R}{C _{V}} = 0.67,$ this gas is made up of
molecules which are

diatomic

mixture of diatomic and polyatomic molecules

monoatomic

polyatomic

Since $\frac{R}{C _{V}} = 0.67 \Rightarrow \frac{C _{P} - C _{V}}{C _{V}} = 0.67$
$\Rightarrow γ = 1.67 = \frac{5}{3}$
Hence gas is monoatomic.
