Question

The temperature at which the r.m.s. velocity of oxygen molecules equal that of nitrogen molecules at `100^(@)C` is nearly.
A. `426.3 K`
B. `456.3 K`
C. `436.3 K`
D. `446.3 K`

Answer 1

Correct Answer - A
`sqrt((3RT)/(32)) = sqrt((3R xx 273)/(28)), T = (273 xx32)/(28), T = (273 xx 32)/(28) = 426.3K`
