What is Meant by the Ideal Gas Law?

In Physics, the ideal gas is defined as the hypothetical gas. It is also known as the universal gas law. The molecules in the gas occupy the negligible space and it should not have any interactions in between. As a result, it should obey the gas law. The ideal gas law describes the relationship between the properties of the ideal gas. It is defined by the formula

PV = nRT


P – Pressure

V – Volume

R – Gas constant 

T – Temperature

n – Number of moles
