Suppose there are two identical gas cylinders. One contains the monatomic gas xenon (Xe), and the other contains an equal mass of the monatomic gas argon (Ar). The pressures in the cylinders are the same, but the temperatures are different. Determine the ratio KEXe/KEAr of the average kinetic energy of an atom of xenon to the average kinetic energy of an atom of argon.
