Calculate the average kinetic energy and RMS velocity of a xenon atom at 166.126 K, which is just 1.075 degrees above the boiling point of xenon at 1 atmosphere pressure. The atomic mass of xenon is 131.293 amu. Because the kinetic energy of a single atom is so tiny, express the KE in units of 10−23 10-23 J.

TB3 Liquid nitrogen is much cheaper than liquid helium. The molecular weight of diatomic nitrogen (N2) is about 28 g/mole and that of atomic helium is about 4 g/mole. One reason for this is that while nitrogen is the most common constituent of the atmosphere, only minute amounts of helium are found in the atmosphere. (Helium is found in natural gas deposits.) Why are only minute amounts of helium found in the atmosphere? TB3 If the absolute temperature of a...
