Calculate the ratio of average velocity ...

Calculate the ratio of average velocity of helium atoms at `27^@C` and methane molecules at `127^@C`.

Text Solution

Verified by Experts

The average velocity `(barC)` is given in terms of molecular weight (M) and absolute temperature (T) as `barC = sqrt((8)/(pi)(RT)/(M))`
For two gases, the ratio is `(barC_(1))/(barC_(2)) = sqrt((T_(1)M_(2))/(T_(2)M_(1)))`
Substituting the values, `(barC_(1))/(barC_(2)) = sqrt((300 xx 16)/(400 xx 4)) = sqrt(3) = 1.73`
