Explain velocity distribution curve ?

Explanation

..At constant speed, fraction of molecules will be remains constant.. which is known as distribution curve which is known as Maxwell and Boltzman.s distribution Curve.
Maxwell and Boltzman indicated that ..distribution of molecules at gases and depend upon temperature and molecule mass of gases...
Maxwell derive formula of number of molecules having certain speed.
Graph of Maxwell Boltzman speed distribution : The curve is speed of molecules against number of molecules. This curve is known as speed distribution of Maxwell Boltzman.

Information of Graph : (i) The fraction of molecules with very low or very high speeds is very small. (ii) The fraction of molecules possessing higher and higher speeds goes on increasing till it reaches the peak and then it starts decreasing. (iii) The maximum fraction of molecules possesses a speed correcponding to the peak in the curve. The speed correcponding to the peak in the curve is called most probable speed `(u_(mp))`.
