Q. If for two gases of moleculer weights

M_{A}

and

M_{B}

at temperature

T_{A}

and

T_{B}

T_{A}

M_{B} = T_{B} M_{A},

then which property has the same magnitude for both the gases.

If for two gases of molar masses MA and MB at temperature TA and TB,TAMB=TBMA, then which property has the same magnitude for both the gases?

The correct option is B RMS speedAs we know,KE=(1/2)mv2here,Given, TA⋅MB=TB⋅MAor TAMA=TBMB;Also, we knowurms=√3RTMurms∝√T/M.so rms speed of both molecules will be same.
