For two gases, A and B with molecular weights `M_(A)` and `M_(B)`. 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:

A

A is at temperature `T_1` and B at `T_2` and `T_1 gt T_2`

B

A is lowered to a temperature `T_1` and `T_1 lt T_2`

C

Both A & B are raised to a higher temperature

D

Both A & B are placed at a lower temperature
