What is the relationship between the average velocity `(v)`, root mean square velocity `(u)` and most probable velocity `(a)` ?

Options

A. `a:v:u::1:1.128:1.224`
B. `a:v:u::1.128:1:1:1.224`
C. `a:v:u::1.128:1.224:1`
D. `a:v:u::1.124:1.228:1`

Answer

A

Explanation

`V_(av):V_(rms):V_(most)` probable `= V:U:a`
`sqrt((8RT)/(pi M)):sqrt((3RT)/(M)):sqrt((2RT)/(M))`
`alpha:V:U = sqrt(2):sqrt((8)/(pi)):sqrt(3) = 1:1.128:1.224`
