Perfect Gas

A perfect gas, or ideal gas, is a theoretical concept in physics and chemistry used to describe a gas that follows certain simplified rules. In a perfect gas, the particles are considered to have no volume and do not attract or repel each other. This allows the gas to expand and fill its container uniformly. The behavior of a perfect gas can be predicted using basic equations, such as the ideal gas law (PV=nRT), where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is temperature.
