The ratio of the most probable speed,average speed,and $RMS$ speed is given by:

The $RMS$ velocity of $CO$ gas molecules at $27^{\circ} C$ is approximately $1000 \ m / s$. For molecules at $600 \ K$, the $RMS$ velocity is approximately (in $m / s$)

If a gas contains only three molecules that move with velocities of $100, 200, 500 \ ms^{-1}$. What is the rms velocity of that gas in $ms^{-1}$?

One way to decrease the average speed of molecules of an ideal gas is ............. .

Which of the following is correct regarding molecular speeds?

At the same temperature,the root mean square velocities of two gases are $v_1$ and $v_2$,and their molar masses are $m_1$ and $m_2$ respectively. Which of the following relations is correct?
