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. WebDec 14, 2015 · P k T = n ( 1 + B n + C n 2 +...), where n is the gas number density. For hydrogen I believe the B coefficient is positive, therefore for a fixed temperature and number density, the pressure is higher. However, if you fix it so that the temperature of the gas is kept constant then so is the rms speed unless you make the gas so dense that one ...
