Animation of experimental verification of Maxwell Boltzmann's distribution law using known concentrations of bismuth vapour and the
velocities at different positions on the glass plate. 


Animated explanation of why do chemical reactions follow distribution law and how evaporation is affected by temperature and why it is a cooling process. 

MaxwellBoltzmann distribution forms the basis of the kinetic theory of gases, and is useful for explaining molecular speed distribution, gas pressure, diffusion and evaporation of liquid. 

This science animation explains the following in detail:
 Correlation between speed, KE, temperature : why does the speed of the molecules in a liquid or gas change continuously
 Maxwell's formula
 Understanding distribution graph : What does area under the curve , low tail, peak, most probable, average, rms speed, speed for lighter molecules
 Case1 : Energy distribution and Temperature :To prove high percentage of molecules will have low energy at low temperatures.
 Interactive graph and molecular motion : Through an interactive graph and increasing motion and collision of molecules understand the significance of graph
 Daily life phenomenon  evaporation : High kinetic energy of the molecules is responsible for the phenomenon of evaporation
 Daily life phenomenon  Chemical Reactions :
 Case 2 : Energy distribution and molar mass : Speed of the molecules is inversely proportional to the molar mass of the molecules
 Experimental verification of Maxwell's law : Experiment explains in details the rotating drum experiment and why spaced patterns of different densities are formed.
 Mathematical analysis of the experiment
Others topics covered are :
 Why collisions cause a change in speed
 Conservation of KE
