Question 929: Thermodynamics & KTG

Question

Equal volumes of two gases are kept in different containers having densities in the ratio 1 : 16. They exert equal pressures on the wall of their respective containers. Then the ratio of their r.m.s. velocities is

Accepted Answer

Pressure $$\mathrm{P}=\frac{1}{3} ho \mathrm{c}^2 \quad 	herefore \mathrm{c}=\sqrt{\frac{3 \mathrm{p}}{ho}}$$
$$	herefore \quad \frac{C_1}{C_2}=\sqrt{\frac{ho_2}{ho_1}}=\sqrt{\frac{16}{1}}=4
$$
