Define RMS, mean and most probable velocities. Write the ratio of these velocities for a given gas. 

What is most probable velocity?

Write the ratio of velocity of red and violet radiations.

Calculate the RMS, average and most probable velocity of SO_2 at 27^@C .

At a given temperature the ratio of RMS and average velocities is

At 27 ^@ C, the ratio of root mean square velocities of ozone to oxygen is

Define (a) RMS (b) average and (c) most probable speeds of gas molecules. Give their interrelationship,

Given the ratio of RMS, average and most probable speeds of gas molecules.

One litre glass bulb contains 2 xx10^(21) molecules of nitrogen at a pessure of 7.57 xx 10^(21) Newton m^(-2) . Find the RMS velocity and temperature of the gas. If the ratio of most probable velocity and RMS velocity is 0.82, find the most probable velocity of nitrogen gas at the same temperature.
