Question

For a gas at a temperature $T$ the root-mean-square velocity $v_{rms},$ the most probable speed $v_{mp},$ and the average speed $v_{av}$ obey the relationship

• A. $v_{av} > v_{rms} > v_{mp}$
• B. $v_{rms} > v_{av} > v_{mp}$
• C. $v_{mp} > v_{av} > v_{rms}$
• D. $v_{mp} > v_{rms} > v_{av}$

Answer 1

Answer: (B)

$v_{rms} > v_{av} > v_{mp}$

Answer 2

$v_{rms} > v_{av} > v_{mp}$
