Kinetic Theory Of Gases Question 28
Question: At room temperature a diatomic gas is found to have an r. m. s. speed of $ 1930m{{s}^{-1}} $ . The gas is:
Options:
A) $ H _{2} $
B) $ Cl _{2} $
C) $ O _{2} $
D) $ F _{2} $
Show Answer
Answer:
Correct Answer: A
Solution:
[a]
$ \
Therefore C=\sqrt{\frac{3RT}{M}} $
$ {{( 1930 )}^{2}}=\frac{3\times 8.314\times 300}{1930\times 1930}\approx 2\times {{10}^{-3}}kg $ The gas is $ H _{2}. $
