Question

For gas at a temperature `T` the root-mean-square speed `v_(rms)`, the most probable speed `v_(mp)`, and the average speed `v_(av)` obey the relationship
A. `V_(mp)gtV_(av)gtV_(ms)`
B. `V_(ms)gtV_(av)gtV_(mp)`
C. `V_(av)gtV_(mp)gtV_(ms)`
D. `V_(mp)gtV_(ms)gtV_(av)`

Answer 1

Correct Answer - B
`V_(rms)`=`sqrt((3kT)/(m)),V_(av)=sqrt((8kT)/(pim))`
`V_(mp)=sqrt((2KT)/(m))`
`therefore V_(ms)gtV_(av)gtV_(amp)`
