According to Kinetic Theory,a Typical Gas Molecule in Thermal Equilibrium

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).[k_B = 1.38 *10 ^{- 23} J/K]
