Two gases of molecular masses MA and MB are at temperatures TA and TB respectively. If TAMB=TBMA, which one of the following properties has the same value for both the gases?

The correct option is B RMS velocityRMS velocity has the same value for both the gases.RMS velocity u=√3RTMThus RMS velocity is directly proportional to square root of temperature and inversely proportional to square root of molar mass. TAMB=TBMATAMA=TBMB√TAMA=√TBMB uA=uBOption B is correct.
