Kinetic Theory Of Gases Question 139
Question: The average translational kinetic energy of a hydrogen gas molecules at NTP will be [Boltzmannยs constant $ k _{B}=1.38\times {{10}^{-23}}J/K] $
Options:
A) $ 0.186\times {{10}^{-20}} $ Joule
B) $ 0.372\times {{10}^{-20}} $ Joule
C) $ 0.56\times {{10}^{-20}} $ Joule
D) $ 5.6\times {{10}^{-20}} $ Joule
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ E _{av}=\frac{f}{2}kT=\frac{3}{2}\times 1.38\times {{10}^{-23}}\times 273 $
$ =0.56\times {{10}^{-20}}J $
