Vedclass · Answer

(A) The three types of molecular speeds are defined as follows:$1$. Root mean square speed: $U_{rms} = \sqrt{\frac{3RT}{M}}$$2$. Average speed: $\bar{v} = \sqrt{\frac{8RT}{\pi M}}$$3$. Most probable speed: $\alpha = \sqrt{\frac{2RT}{M}}$Comparing the coefficients:$U_{rms} = \sqrt{3} \approx 1.732$$\bar{v} = \sqrt{\frac{8}{3.14}} \approx \sqrt{2.546} \approx 1.596$$\alpha = \sqrt{2} \approx 1.414$Therefore,the correct order is $U_{rms} > \bar{v} > \alpha$.
