1.What is the RMS speed of Helium atoms when the temperature of the Helium gas is 209 K? (Possibly useful constants: the atomic mass of Helium is 4.00 AMU, the Atomic Mass Unit is: 1 AMU = 1.66×10-27 kg,constant is: kB = 1.38×10-23 J/K.)

2.What would be the RMS speed, if the temperature of the Helium gas was doubled?

Laser Cooling of Atoms: In the simplest versions of laser cooling, a gas of atoms can be cooled from room temperature (?300 K) to about 1 × 10-4 K through the absorption of light. The absorbed light transfers momentum to the atoms, thereby slowing down those atoms that are moving in the direction of the incoming laser beam. The following questions refer to a gas of rubidium atoms. (a) The average speed of atoms in the gas phase is directly...
