\mathrm{\text { Rate of diffusion } \alpha \lambda \alpha \text { U AVg }}

\mathrm{\begin{aligned} & \alpha \frac{1}{\sqrt{2} \pi \sigma^2 N} \times U_{A V g} \\ & \alpha \frac{1}{\sqrt{2} \pi \sigma^2 N} \\ & \propto \frac{U A V g(K T)}{\sqrt{2} \pi \sigma^2 P} \end{aligned}}

\mathrm{\text { Rate of diffuaion } \propto \frac{T^{3 / 2}}{p}}

\mathrm{\frac{\text { r final }}{\text { r inital }}=\frac{(8)^{3 / 2}}{(4)}=4}
