Question 889: Thermodynamics & KTG

Question

Two monatomic ideal gases A and B of molecular masses '$$m_1$$' and '$$m_2$$' respectively are enclosed in separate containers kept at the same temperature. The ratio of the speed of sound in gas A to that in gas B is given by

Accepted Answer

$$\mathrm{v}=\sqrt{\frac{3 \mathrm{RT}}{\mathrm{M}}}$$ or $$\mathrm{v} \propto \sqrt{\frac{1}{\mathrm{M}}}$$ at constant $$\mathrm{T}$$
$$	herefore \frac{\mathrm{v}_1}{\mathrm{v}_2}=\sqrt{\frac{\mathrm{m}_2}{\mathrm{~m}_1}}$$

Answer

$$\sqrt{\frac{\mathrm{m}_2}{\mathrm{~m}_1}}$$

Answer

$$\frac{\mathrm{m}_1}{\mathrm{~m}_2}$$

Answer

$$\sqrt{\frac{\mathrm{m}_1}{\mathrm{~m}_2}}$$

Answer

$$\frac{\mathrm{m}_2}{\mathrm{~m}_1}$$
