A gas is cooled and trapped in a two-dimensional region by laser beams and magnets. The speed distribution function of the gas molecules obeys the two-dimensional Maxwell-Boltzmann distribution law,
f(v)=2π(m2πkB T)ve−mv22kB T
where m is the mass of a gas molecule, T is the temperature, and v is the speed. What is the average speed of the gas molecule?
An ideal diatomic gas with n = 1 mol has a molar mass of 32 g/mol and is in a container with a volume of V, pressure p, and temperature T. Another container with the same volume V contains a monatomic gas with n=1 mol, a molar mass of 8 g/mol, a pressure p, and a temperature T. What is the ratio of the RMS speed of the first gas to the second?
A sample of 3 mol of diatomic gas is measured to have a temperature of 300 K. If the mass of the gas is 0.048 kg, what is the approximate average speed of the molecules in the gas ?
