#### Solution Preview

The average kinetic energy of a gas molecule due to the temperature is:

E=(3/2)*k*T

Where k is the Boltzman constant and T is the temperature.

So we see that both gases' molecules will have the same kinetic energy (it only depends on ...

#### Solution Summary

The kinetic theory of gases to determine temperatures are discussed. Inverse ratios of the square roots are examined.
