Average speed (c­_avg)

What is the Average speed of gas molecules

As per the kinetic theory of gases, each molecule is moving with an altogether different velocity. Let ‘n’ molecules be present in a given mass of gas, in which n₁ molecules have a speed of v_1, n₂ molecules have a speed of v_{2, ,}n_n molecules have a speed of v_n.

i.e. Average velocity v_avg = √8RT/πM

Where, R = gas constant

T= Temperature

M= molar mass

since R, M and pie are constant
