According to kinetic theory, a typical gas molecule in thermal equilibrium at room temperature has a kinetic energy K = 6.00 × 10^?21 J, regardless of mass. Estimate the speed at room temperature of a hydrogen molecule H2 (m = 3.34 × 10^?27 kg) and a xenon atom (m = 2.00 × 10^?25 kg). [kB = 1.38 × 10^?23 J/K]
