Kinetic theory explains the behaviour of gases based on the idea that the gas consists of rapidly moving atoms or molecules.
In solids the molecules are very tightly packed as inter molecular space is not present In liquids inter molecular spaces are more as compared to solids and in gases the molecules are very loosely packed as intermolecular spaces are very large.
The random movement of molecules in a gas is explained by kinetic theory of gases.
We will also see that why kinetic theory is accepted as a success theory.
Kinetic theory explains the following:-
Molecular interpretation of pressure and temperature can be explained.
It is consistent with gas lawsand Avogadro’s hypothesis.
Correctly explains specific heat capacities of many gases.
