Ideal gas law was first started by Benoit Paul Emile Clapeyron.
It states that the product of pressure and volume of a gas is directly proportional to the product of temperature and Gas constant.
The empirical form of ideal gas law is written as
Where is the pressure of ideal gas, is the volume of ideal gas, is the amount of substance, is the Universal gas constant and is absolute temperature. The value of is constant that is .
