Answer on Question #43116 Physics Molecular Physics|ThermodynamicsQuestion.Calculate the root mean square velocity of molecule of hydrogen gas at room temperature 27cand calculate the mean kinetic energy of one molecule and one mole.Given: = 27 = 300 (2 ) = 3.34 1027 (2 ) = 2 103 = 1 Find: = ? (1 ) = ? (1 ) = ?Solution.From thermodynamics it's known that the average kinetic energy of the gas is proportional totemperature: =32 = 1.38 1023 is the Boltzmanns constant; is the temperature. = = 8.31the gas constant; = 6.02 1023 1 is the Avogadro constant.So, th
