Assume a gas of molecular mass M g/molecule obeys the Maxwell Boltzmann distribution of speeds at temperature T. If u2> u1, the ratio of the number of molecules at speed u2 to the number at speed u1
a) is always less than one.
b) is always greater than one.
c) can be either greater than one or less than one.
d) will decrease if the temperature increases for fixed m.
e) will not change if mass m increases for fixed T.
