For a gas at a temperature T the root-mean-square velocity \[{{\text{v}}_{rms}},\] the most probable speed \[{{\text{v}}_{mp}},\] and the average speed \[{{\text{v}}_{a\text{v}}}\] obey the relationship

A) \[{{\text{v}}_{a\text{v}}}>{{\text{v}}_{rms}}>{{\text{v}}_{mp}}\]

B)        \[{{\text{v}}_{rms}}>{{\text{v}}_{a\text{v}}}>{{\text{v}}_{mp}}\]

C) \[{{\text{v}}_{mp}}>{{\text{v}}_{av}}>{{\text{v}}_{rms}}\] 

D) \[{{\text{v}}_{mp}}>{{\text{v}}_{rms}}>{{\text{v}}_{av}}\]
