Homework Statement
Aluminium atoms at 1173K enter a vacuum chamber. Calculate the most probable speed for the atoms.
Homework Equations
vmp=[tex]\sqrt{}[/tex](2kT/m)
The Attempt at a Solution
The molar mass of aluminium is 0.0270kg mol^-1, so
vmp=[tex]\sqrt{}[/tex](2*1.381*10^-23JK^-1)*1173K/0.0270kg mol^-1=1.1*10^-9ms^-1
Which is a really tiny quantity and it seems unrealistic that particles at such a high temperature would move that slowly. I've used SI units though so I can't see where I would have gone wrong. Any help would be appreciated. Thanks
