In the current lecture we will discuss about the Maxwell’s distribution law of speed. This topic is related to thermodynamics in which we mainly discuss about the Maxwell’s distribution law of speed, and different speed of gas molecules and functions. For deriving the Maxwell’s distribution law we assume that the number of molecules in a fixed volume of gas is very high, and they move with the speeds ranging from 0 to infinitive. The molecular density remains the same throughout each element of the entire volume of gas. In the steady state, at a fixed temperature the number of molecules remains the same in the different range of velocities. Each volume element can have all possible speed of the molecule. In the present lecture we also discuss about the different speed of gas molecules and functions in which we discuss about the curve between f(c) and speed c, most probable speed, peak height of P(c) curve, average speed, root mean square speed or rms speed and the number of molecules in the energy range E and E + dE. This lecturer is very useful for the students of class XI, XII, B.Sc., M.Sc., and engineering students. The topic is also very useful for the students preparing for NEET, IIT-JEE, CSIR NET, GATE and other competitive exams. Here we have explained everything about the Maxwell’s distribution law of speed in Hindi and in English language, so it is bilingual lecture. This topic is related to Thermodynamics or thermal physics. http://blog.sacademy.co.in https://www.sacademy.co.in / sacademy-vimal / sacademy9 / sacademy9 / sacademy9 / sacademy9
