Explain boyle's Law on the basis of the kinetic theory of matter.
Explanation of Boyle’s Law on the basis of kinetic theory of matter.
According to kinetic theory of matter, the number of particles present in a given mass and the average kinetic energy is constant.
If the volume of given mass of a gas is reduced to half of its original volume. The same number of particles will have half space to move.
As a result, the number of molecules striking the unit area of the walls of the container at given time will get doubled of the pressure will also get doubled.
Alternatively, if the volume of a given mass of a gas is doubled at constant temperature, same number of molecules will have double space to move. Thus, number of molecule striking the unit area of the walls of container at a given time will become one half of original value. Thus, pressure will also get reduced to half of original pressure. Hence, it is seen that if pressure increases, volume of a gas decreases at constant temperature and this is Boyle’s law.
