Question

In maxwell-boltzmann distribution what is the uses of Vrms and Vavg and V most probable speeds and when we use each of them

Answer 1

Ans=

1. V_RMS = Gases consist of atoms or molecules that move at different speeds in random directions. The root means square velocity (RMS velocity) is a way to find a single velocity value for the particles. It gives the magnitude of the single mean velocity when molecules move in a random direction with different velocities.

2. V_AVG  = It gives the significant measurement of the kinetic energy of a molecule of mass m traveling at a speed v is E_k=12mv², which implies that the mean kinetic energy of a collection of molecules, Ek, is the average of this quantity. It follows from the relation 1/2mv²rms = E_k.

3. V most probable speed = It is the most probable speed of the molecules and is the maximum value for the velocity distribution curve. V _MPS is the smallest of the three speeds is due to the asymmetry of the curve.
