A) \[3.0\]
B) \[2.4\]
C) \[0.9\]
D) \[0.6\]
Correct Answer: D
Solution :
\[u=\sqrt{\frac{3RT}{M}}\] For the same gas at two different temperatures, \[\frac{{{u}_{1}}}{{{u}_{2}}}=\sqrt{\frac{{{T}_{1}}}{{{T}_{2}}}}\] \[\frac{0.3}{{{u}_{2}}}=\sqrt{\frac{300}{1200}}=\frac{1}{2}\] \[{{u}_{2}}=0.6m{{s}^{-1}}\]You need to login to perform this action.
