KE=3/2 kb*Temp
so if you solved the first part, you must have used the formula to find the KE of the molecules (1/2 m v^2).
So use the same formula to find Temp when v=speed of bullet. (change to m/s)
a) Which is the greater speed, that of a bullet fired from a high powered M-16 rifle (2180 mi/hr) or the root mean square speed of H2 molecules at 25 degrees Celsius.
I completed part a) however I don't know how to answer part b)
b) At what temperature are the Urms of H2 and the speed of the M-16 rifle bullet given in part a) the same?
