The mean square s A. 1/T
Root mean square velocity of gas is given as
where R=gas constant whose value is 8.31 J/mol K.
T=temperature of gas.
M= molar mass of molecule of gas
Squaring both side of equation (I) we are removing the square root and
we will get mean square velocity which is,
So, mean square speed is directly proportional to temperature as for a
given gas its molar mass will not change.
