Speed of a gas molecule
WebWe can find the rms speed of a nitrogen molecule by using the equation. vrms = √– v2 = √3kBT m, but we must first find the mass of a nitrogen molecule. Obtaining the molar mass of nitrogen N2 from the periodic table, we find. m = M NA = 2(14.0067) × 10−3kg/mol) 6.02 × 1023mol-1 = 4.65 × 10−26kg. WebDec 10, 2024 · Well, molecules of the gas can have same speed only if they will be static -- or at absolute zero($0K$ or $-273°C$)[but it is only possible in theory]. It is simple physics of vector movement -- sum of forces applied towards one molecule from surrounding molecules which are also in th state of motion(sum of kinetic energy in limited volume ...
