Ideal gases

An ideal gas is a theoretical concept where gas particles are tiny, spherical, and have no size or intermolecular forces, moving randomly and independently. They obey the gas laws perfectly, meaning their pressure, volume, and temperature relate predictably. In reality, gases behave like ideal gases under many conditions, especially at low pressures and high temperatures. The ideal gas model simplifies understanding gases' behavior, making it useful for calculations and predictions in physics and chemistry, even though real gases may deviate slightly due to particle size and interactions.
