Consider neon, a noble gas whose molecules consist of single atoms of atomic mass 0.02 kg/mol. Avogadro's number is 6.02 × 1023 mol-1, and Boltzmann's constant is 1.38×10-23 J/K. The average kinetic energy of this neon atom is 400 K.
What is the root-mean-square speed of a neon atom under such conditions?
