   In an orbital laboratory, a planetary probe stores neon gas in Chamber Alpha at 300 K and argon gas in Chamber Beta at 600 K. An autonomous technician reports that the lighter neon atoms must possess greater average kinetic energy because lighter particles travel with higher average speeds. According to kinetic molecular theory, which statement correctly evaluates the apprentice technician's claim?

   • A) The argon atoms in Chamber Beta possess a higher average kinetic energy because average kinetic energy is directly proportional to absolute temperature regardless of particle mass.
   • B) The neon atoms in Chamber Alpha possess a higher average kinetic energy because low-mass gas particles inherently concentrate thermal energy more effectively.
   • C) The atoms in both chambers possess identical average kinetic energy because ideal gas particles equalize kinetic energy across all closed containers.
   • D) The argon atoms in Chamber Beta possess lower average kinetic energy because heavier noble gas atoms resist acquiring translational kinetic energy.
