Simple Context about Gas Laws
Simple Context about Gas Laws
The three fundamental gas laws discover the relationship of pressure, temperature, volume and amount of gas. It is being used to determine the densities of gases and in stoichiometric calculations. The coolants/refrigerants in your refrigerator, hot air balloons in the sky, and combustion engines in vehicles, all are based on the ideal gas law. Gas laws are important because they can be used to determine the parameters of a mass of gas using theoretical means.

Where,
P is the pressure of a gas.
V is the volume of gas.
