The Maxwell speed distribution function is given by: f(v): = 3 m (2πKBT) 4πv² e-mv²/2kgT i. Show that the average speed of the molecule is given by (v) = √√8kBT/лm. A valve connecting a first chamber, containing a mixture of 10% ³He and 90% 4He, is opened to a second chamber, which is under vacuum. The diameter of the valve is small compared to the mean free path of the atoms, and the number of atoms escaping from the first to the second chamber will depend on the species. iii. ii. Calculate the ratio of the number of ³He and 4He atoms that have escaped the first chamber. How many times, approximately, does this procedure need to be repeated to produce a mixture of 30% ³He?

A mixture of gases consists of 0.4 kg of oxygen, 0.7 kg of carbon dioxide, and 0.2 kg of helium. This mixture is maintained at 100 kPa and 27 °C. Determine the apparent molecular weight of this mixture the volume it occupies, the partial volume of the oxygen, and the partial pressure of the helium. (
At 298K, N2 molecules have a mean speed of 475 m/s. As a consequence, the probability to randomly pick 1 molecule at 475.00 m/s is extremely high. Select one: True False
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 %3D 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-m²/s²). What is the rms speed of O, molecules at 411 K? rms speed: m/s What is the rms speed of He atoms at 411 K? rms speed: m/s
