According to Kinetic Theory, a Typical Gas Molecule in Thermal

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]
