Ideal gas equation: Learn the equation of state for ideal

Learn the equation of state for ideal gases that relates pressure, volume, gas quantity, and absolute temperature. See how to use the ideal gas law for solving problems, comparing states, and finding partial pressure. What is Ideal Gas Law? The ideal gas law, also known as the general gas equation, is an equation of the state of a hypothetical ideal gas. Although the ideal gas law has several limitations, it is a good approximation of the behaviour of many gases under many conditions. The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions, although it has several limitations. Ideal gas law, relation between the pressure P, volume V, and temperature T of a gas in the limit of low pressures and high temperatures, such that the molecules of the gas move almost independently of each other. In such a case, all gases obey an equation of state known as the ideal gas law: PV =
