The information on the proceeding slide leads to an equation relating gas speed to temperature. vrms Root Mean Squared Velocity R Universal Gas Constant (R = 8.31) kb Boltzman Constant (kb = 1.38 10-23) T M Temperature in Kelvin Molar mass (kg/mol)
Mass of one mole of gas. Divide the mass number (grams/mole) by 1000 to convert kilograms/mole. vrms = 3 = 3 Molecular mass (kg/atom)
Mass of one molecule of gas. Multiply the mass number (amu's) by the conversion to kilograms (1.6610-27 kg/amu) RHJ...
