Mean root square speed
The mean speed , most probable speed (mode) vp, and root-mean-square speed can be obtained from properties of the Maxwell distribution. This works well for nearly ideal, monatomic gases like helium, but also for molecular gases like diatomic oxygen. This is because despite the larger heat capacity (larger internal energy at the same temperature) due to their larger number of degrees of freedom, their translational kinetic en… WebThe relation between root mean square speed (Vrms) and most probable speed (Vp) for the molar mass M. asked Jul 12, 2024 in Physics by GovindSaraswat (45.4k points) jee main 2024; 0 votes. 1 answer. V; vrms and vP respectively denote the mean speed; root mean square speed and the most probable.
