According to Kinetic Theory, a Typical Gas Molecule in Thermal

question 24

Short Answer

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]
