Question

If Co and C represent the rms speed of monoatomic gas molecules and the speed of sound in that gas, then

co > C
Co= C
Co < C
None of these​

Answer 1

Answer:

co>c

Explanation:

Answer 2

Given:

$Co$ and $C$ are rms speed of Monoatomic gas and speed of the sound in that gas

To Find:

Relation between root mean square speed and speed of the sound

Explanation:

The root mean square speed of the monoatomic gas is expressed in this equation first-

$rms = Co = \sqrt[]{ \dfrac{3RT}{M} }$

And Speed of the sound in monoatomic gas is expressed in this second equation-

$C = \sqrt[]{\dfrac{5RT}{3M} }$

For monoatomic gas = Υ = $\dfrac{5}{3}$

By solving both equation

We get $Co > C$

First option is the answer of this question
