A) 300 K
B) 600 K
C) 1200 K
D) 2400 K
Correct Answer: D
Solution :
[d] \[{{V}_{rms}}=\sqrt{\frac{3RT}{M}}\] \[{{V}_{rms({{O}_{2}})}}={{V}_{rms(He)}}\] \[\sqrt{\frac{3RT{{o}_{2}}}{M{{o}_{2}}}}=\sqrt{\frac{3R{{T}_{He}}}{{{M}_{He}}}}\] Or \[\frac{T{{o}_{2}}}{M{{o}_{2}}}=\frac{{{T}_{He}}}{{{M}_{He}}}\] \[\therefore T{{o}_{2}}=\frac{300\times 32}{4}=2400K\]You need to login to perform this action.
