The average kinetic energy of the molecules in a gas sample depends only on the temperature, ?. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed rms speed=3??ℳ⎯⎯⎯⎯⎯⎯⎯⎯⎯√ where ?=8.314 J/(mol⋅K) and ℳ is molar mass in kilograms per mole. Note that a joule is the same as a kilogram‑meter squared per second squared (kg·m2/s2). What is the rms speed of O2 molecules at 357 K? What is the rms speed of HeHe atoms at 357357 K?
