Ideal gas

An ideal gas is a theoretical concept in physics and chemistry that describes a gas whose particles are in constant, random motion and do not interact with each other. In this model, the size of the gas particles is negligible, and there are no attractive or repulsive forces between them. Ideal gases obey specific laws, like Boyle's and Charles's laws, which relate pressure, volume, and temperature. While no real gas perfectly fits this model, many gases behave similarly to an ideal gas under certain conditions, such as low pressure and high temperature.
