Wave Mechanics Question 67
Question: Sound velocity is maximum in
[Pb. CET 2000; RPMT 2000]
Options:
A) $ H _{2} $
B) $ N _{2} $
C) $ He $
D) $ O _{2} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ v=\sqrt{\frac{\gamma RT}{M}} $
Therefore $ v\propto \frac{1}{\sqrt{M}} $ . Since $ M $ is minimum for $ H _{2} $ so sound velocity is maximum in H2.
