For two gases, A and B with molecular weightsMAandMB, it is observed that at a certain temperature, T, the mean velocity of A is equal to the root mean square velocity of B. Thus, the mean velocity of A can be made equal to the mean velocity of B, if

Options:

Answer:
B
Solution:

UAve-A=8RTπMA
Urms-B=3RTMB
So83π=MAMB
ForUave.-A=8RT2πMA
Uave.-B=8RTπMB
T2T=MAMB=83π
SoT2=83π.T
orT2<T.
