Concept introduction:
Hybridization refers to mixing of orbitals. The orbitals of different atoms overlap with each other and form a set of new orbitals called hybrid orbitals. The number of orbitals that are combined equal to the number of hybrid orbitals formed by combination.
An isolated atom remains in excited state and comes back to ground state. In this situation, it is difficult for orbitals to hybridize.
Hybridization is a hypothetical concept. It refers to mixing of atomic orbitals and the resultant orbitals formed are known as hybrid orbitals. After hybridization, the orbitals cannot be distinguished individually. Based on hybridization one can predict the geometry of the molecule though some deviations do exist.

Concept introduction:
Ideal gas equation:
Any gas is described by using four terms namely pressure, volume, temperature and the amount of gas. Thus combining three laws namely Boyle’s, Charles’s Law and Avogadro’s Hypothesis the following equation could be obtained. It is referred as ideal gas equation.
Under some conditions gases don not behave like ideal gas that is they deviate from their ideal gas properties. At lower temperature and at high pressures the gas tends to deviate and behave like real gases.
Boyle’s Law:
At given constant temperature conditions the mass of given ideal gas in inversely proportional to its volume.
Charles’s Law:
At given constant pressure conditions the volume of ideal gas is directly proportional to the absolute temperature.
Avogadro’s Hypothesis:
Two equal volumes of gases with same temperature and pressure conditions tend to have same number of molecules with it.
