Question

For a gas at thermal equilibrium the average speed v, the most probable speed vp, and the root-mean-square speed vrms are in the order

Answer 1

Answer:

Root mean square speed

v

rms

=

m

3kT

Most probable speed

v

mp

=

m

2kT

Average speed

v

av

=

πm

8kT

u

mp

:u

av

:u

rms

=1:1.128:1.224

So, v

rms

>v

av

>v

mp
