Question

The root mean square velocity of an ideal gas at constant pressure varies with density as

Answer 1

Sol.----------
RMS VELOCITY=
$\sqrt{3 rt \div m \:}$
Also p.m=dRT
then RT/M in Urms
Urms=
$\sqrt{3p \div d}$
then Urms is directly proportional to
$1 \div \sqrt{d}$



I Hope it will satisfy u

Answer 2

V RMS is directly proportional to 1/√d
