MCQ
For a gas, $\frac{\text{R}}{\text{C}_{\text{V}}}=0.67$ The gas is made up of molecules, which are:
- ✓Monoatomic.
- BDiatomic.
- CTriatomic.
- DPolyatomic.
✓
Answer
Correct option: A.
Monoatomic.
$\frac{\text{R}}{\text{C}_{\text{V}}}=0.67=\frac{2}{3}$
$\text{C}_{\text{V}}=\frac{3}{2}\text{R}$
$\text{C}_{\text{V}}=\frac{3}{2}\text{R}$
