the ideal gas law PV=nRT only can used on the ideal gas, right?
if the we want consider the real gas...
what equation should we used??

The ideal gas law, PV=nRT, assumes that gases behave ideally and do not interact with each other. However, real gases deviate from this behavior under certain conditions, making it necessary to explore alternative equations that take into account these deviations.
Examples of real gas laws include the van der Waals equation, the Redlich-Kwong equation, and the Soave-Redlich-Kwong equation. These equations incorporate factors such as intermolecular forces and molecular size to better describe the behavior of real gases.
The ideal gas law assumes that gases have no volume and do not interact with each other, while real gas laws take into account the volume of gas molecules and the attractive and repulsive forces between them. Real gas laws also include correction factors to account for non-ideal behavior.
Real gas laws are commonly used in the design and operation of industrial processes, such as in the production of liquefied natural gas. They are also important in the development of new technologies, such as fuel cells and gas storage systems.
Temperature and pressure have a significant impact on the behavior of real gases. As temperature decreases and pressure increases, real gases tend to behave more like ideal gases. However, at high pressures and low temperatures, real gases can deviate significantly from ideal behavior.
