A lighter molecule will move faster than a heavier molecule

Reference no: EM13698038

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 Ne molecules at 361 K?
