Question- The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule.
Where R=8.314 J/(mol•K) and ? is molar mass in kilograms per mole. Note that a joule is the same as a kg•m2/s2.
What is the rms speed of N2 molecules at 361K?
What is the rms speed of He atoms at 361 K?
Please answer only if you are 100% confident
