Question
The ratio of the speed of sound in nitrogen gas to that in helium gas, at 300 K is
Options
A.
B.
C.(√3) / 5
D.(√6) / 5
Solution
Speed of sound in an ideal gas is given by
v =
∴ v ∝
[T is same for both the gases]
∴
= √3 / 5
γN2 =
[Diatomic]
γHe =
[Monoatomic].
v =
∴ v ∝
[T is same for both the gases]∴
= √3 / 5 γN2 =
[Diatomic]γHe =
[Monoatomic].Create a free account to view solution
