The total number of co-ordinate or independent quantities required to describe completely the position and configuration of a dynamic system is known as number of degree of freedom of the system. It is represented by f and expressed as (I) In case of monoatomic gas, such a helium, neon, organ, kripton, etc have translational degree […]
All matter is made up of molecules. The molecules of a gas are in state of rapid and continuous motion. Their velocity depends on temperature. Using this molecular motion, various properties of a gas like pressure, temperature, energy etc, can be explained. Hence this theory is called kinetic theory of gases which was developed by
Boyle’s Law It state that for a given mass of a gas at constant temperature, the volume(V) of that mass of gas is inversely proportional to its pressure(p). Charles’ Law It state that for a given mass of an ideal gas at constant pressure, volume (V) of a gas is directly proportional to its absolute
The molecules of gas are far from each other and their mutual interactions are negligible except when two molecules collide. So, gases at low pressure and high temperature much above that at which they (liquify or solidify) follow a relation pV = KT -(i) Behaviour Of Real Gas and Ideal Gas An ideal gas is
In 20th century, Richard Feynman one of the great physicists discovered that matter is made up of atoms. About 2000 year ago John Dalton suggested that the smallest constituents of an element are atoms and they cannot be separated any further. Atoms of one element are identical but differ from those of other elements. A
