The maximum in the curves describing the Maxwell-Boltzmann distribution of speeds corresponds to

Options

A. root mean square speed
B. mean square speed
C. average speed
D. most probable speed

Answer

D

Explanation

The maximum in the curve represents the speed possessed by the maximum number of molecules. This speed is called the most probable speed.

The graph shows that when `T` is neither high nor low , the number of molecules possessing very high and very low speed is very small. Most of the molecules possess most probable speed.
