WebJan 29, 2024 · The kinetic theory of gases correlates between macroscopic properties and microscopic phenomena. Kinetics means the study of motion, and in this case motions of gas molecules. At the same temperature and volume, the same numbers of moles of all gases exert the same pressure on the walls of their containers. This is known as … WebFeb 22, 2024 · The rms velocity depends on both the molar mass and the temperature, so it is easiest to just calculate the rms velocity for each gas, v rms for N 2 is 515 m/s and for O 2 is 521 m/s. b) Hydrogen is larger. If …
