A cylinder contains a mixture of helium and argon gas in equilibrium at a temperature of 247 ? C. Boltzmann's constant is 1.38066 × 10 ?23 J/K, and Avogadro's number is 6.02 × 10 23 mol ?1 .
What is the average kinetic energy of each type of molecule? (Answer in units of J)
What is the rms speed of helium? (Answer in units of km/s)
What is the rms speed of argon? (Answer in units of km/s)
