Question

For a gas $\frac{R}{{{C}_{\upsilon }}}=0.67.$ This gas is made up of molecules which are:

• A. monoatomic
• B. polyatomic
• C. mixture of diatomic and polyatomic molecules
• D. diatomic

Answer 1

Answer: (A)

monoatomic

Answer 2

Given $\frac{R}{{{C}_{v}}}=0.67$ so ${{C}_{v}}=\frac{R}{0.67}=1.5R=\frac{3}{2}R$ This value corresponds to monoatomic.
