At a certain temperature ,molecules of methane gas CH4 have an average velocity of 0.098m/s. What is the average velocity of carbon dioxide molecules at this same temperature?
At the same temperature all molecules have the same kinetic energy: 0.5 m(CH₄) * V₁² = 0.5 x m(CO₂) x V₂² 0.5 x 16 x (0.098)² = 0.5 x 44 x V₂² V₂ = 0.059 m/s
