Question
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed 3 RT rms speed where R = 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-m?Is?). What is the rms speed of F, molecules at 303 K? 2 rms speed: m/s What is the rms speed of He atoms at 303 K? rms speed: m/s
