Question
Doubling the pressure at constant temperature for a gas but the molecular weight, what will be the effect on velocity?
✓
Answer
According to the following formula, the root mean square velocity depends on temerpature and not on pressure.
$C _{ rms }=\sqrt{\frac{3 RT }{ M }}$
Therefore doubling the pressure will have no effect.
$C _{ rms }=\sqrt{\frac{3 RT }{ M }}$
Therefore doubling the pressure will have no effect.
