At what temperature is the root-mean-square speed of nitrogen molecules equal to the root-mean-square speed of hydrogen molecules at 46 oC? (Hint: The molar mass of hydrogen atoms is 1.008 g/mol and of nitrogen atoms is 14.007 g/mol. The molar mass of H2 is twice the molar mass of hydrogen atoms, and similarly for N2.) The answer is in degree C.

The root-mean-square speed of the molecules in a gas in an
indication of the temperature of this gas. Shown below is the
spectrum of three stars of different surface temperature. The
x-axis displays the wavelength of the light emitted by the star.
Shorter wavelength corresponds to higher energy of the gas, longer
wavelength to lower energy. Stars are primarily made of Hydrogen.
Calculate vrms for the three stars shown in the figure. How do
these values compare to the rms...
