Average velocity:

The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another.

→→→ average velocity= √(8RT)÷ πM (whole root)

Most probable velocity:

Most Probable Velocity is defined as the velocity with which maximum number of the particles in a gas move with. In a gas there are millions of particles. The speed travelled by the majority of gas particles is defined as Most Probable Speed.

→→→ most probable velocity = √(2RT)÷M (whole root)

RMS velocity:

The square root of the mean of squares of the velocity of individual gas molecules.

→→→ RMS velocity = √(3RT)÷M (whole root)
