The Ideal Gas Law, PV = nRT, is a fundamental equation in chemistry and physics, describing the behavior of gases in terms of pressure, volume, and temperature. It is based on the Kinetic Molecular Theory, which explains gas properties at the microscopic level. This law is essential for calculating molar volume and mass, and understanding the limitations when dealing with real gases.
