Chemistry - Ideal Gas Question with Solution | TestHub

Average velocity of a gaseous molecule$=\sqrt{\frac{8\mathrm{R}\mathrm{T}}{\mathrm{\pi }\mathrm{M}}}$
If the absolute temperature is doubled, then new
Average velocity becomes$=\sqrt{\frac{8\mathrm{R}.2\mathrm{T}}{\mathrm{\pi }\mathrm{M}}}$
New average velocity$=\sqrt{2}.\sqrt{\frac{8\mathrm{R}\mathrm{T}}{\mathrm{\pi }\mathrm{M}}}$
New average velocity$=1.4\times$original average velocity.
