Question

rms velocity pressure per depend ha right ya wrong

Answer 1

$pv = nrt \\ rt = \frac{pv}{n} \\ v = \sqrt{ \frac{3rt}{m} } \\ v = \sqrt{ \frac{3pv}{mn} } \\ v \alpha \sqrt{ p}$
hope it helps.

Answer 2

Pressure=force/area, force=mass * acceleration, acceleration is rate of change of velocity. Thus pressure is directly proportionate to pressure.
