The relationship between the velocity (U) of gas molecules and their relative molecular mass (M) is shown by the equation

A.

U = (kM)\(\frac{1}{2}\)

B.

U = (kM)2

C.

U = \(\sqrt{\frac{k}{m}}\)

D.

U = \(\frac{k}{m}\)

Correct answer is C

The relationship between (U) of a gas molecule and the relative molecular mass is \(\bar{U}\) = (\(\frac{k}{m}\))\(^{\frac{1}{2}}\)

or \(\bar{U}\) = \(\sqrt{\frac{k}{m}}\)
