JEE Mains · Physics · STD 11 - 12 . kinetic theory of gases
A mixture of one mole of monoatomic gas and one mole of a diatomic gas (rigid) are kept at room temperature \(\left(27^{\circ} \mathrm{C}\right)\). The ratio of specific heat of gases at constant volume respectively is _______.
- A \(\frac{7}{5}\)
- B \(\frac{3}{2}\)
- C \(\frac{3}{5}\)
- D \(\frac{5}{3}\)
Answer & Solution
Correct Answer
(C) \(\frac{3}{5}\)
Step-by-step Solution
Detailed explanation
\(\frac{\left(\mathrm{C}_{\mathrm{v}}\right)_{\text {mono }}}{\left(\mathrm{C}_{\mathrm{v}}\right)_{\text {dia }}}=\frac{\frac{3}{2} \mathrm{R}}{\frac{5}{2} \mathrm{R}}=\frac{3}{5}\)
