Asked by Chris
Is average speed (u) the same as root mean square velocity? I found a formula for root mean square velocity which I know is also used for average speed:
(3RT/MM)^1/2
Is that right?
I don't know what that is supposed to be an average OF, but is all likelihood it is a root mean square. The mean or average speed is not the same.
Are you sure you did not mean to write
[3 R T/ M ]^(1/2) ?
That is the room mean square speed of an ideal gas. M is the molar mass of the molecule.
Yes, that's what I meant. My book denotes molar mass as MM. Thank you
