WebApr 10, 2024 · The average velocity of gas molecules is the speed at which they move around in a space. This can be affected by various factors such as temperature, pressure, and the type of gas. The average velocity is important because it determines how fast a gas will expand or contract in response to changes in these conditions. WebAverage 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 n 1 molecules have a speed of v 1, n 2 molecules have a speed of v 2, , n n molecules have a speed of v n.
