The general gas laws applied toreal gases is:
pV= nRT
For non-ideal gases the van der Waals law is applicable.
Ideal gases are hypothetical gases that follow the gas laws perfectly under all conditions, exhibiting no intermolecular forces and occupying no volume. In contrast, non-ideal gases deviate from these behaviors due to factors such as intermolecular attractions and the volume occupied by gas molecules, especially at high pressures and low temperatures. These deviations lead to differences in properties like pressure, volume, and temperature relationships, making real gases behave differently from the ideal gas law predictions.
An ideal gas is a theoretical gas composed of a set of randomly-moving, non-interacting point particles. The ideal gas concept is useful because it obeys the ideal gas law. At normal conditions such as standard temperature and pressure, most real gases behave qualitatively like an ideal gas. Many gases such as air, nitrogen, oxygen, hydrogen, noble gases, and some heavier gases like carbon dioxide can be treated like ideal gases within reasonable tolerances.
Ideal gases are gases with negligible intermolecular forces and molecular volumes. Real gases have intermolecular forces and have definite volumes at room temperature and pressure (RTP).
Two types of non-ideal solutions are ideal mixtures and non-ideal mixtures. Ideal mixtures follow Raoult's Law, where the vapor pressure of each component is directly proportional to its mole fraction in the solution. Non-ideal mixtures do not obey Raoult's Law due to interactions between the components, such as deviations from ideal behavior or the formation of new chemical species.
Gases behave non-ideally at low temperatures and high pressures due to increased intermolecular forces and reduced kinetic energy. At low temperatures, gas molecules move more slowly, allowing attractive forces to have a greater influence, leading to deviations from ideal behavior. Additionally, at high pressures, the volume of gas molecules becomes significant compared to the overall volume of the gas, causing assumptions of point-like particles in the ideal gas law to break down. These factors result in discrepancies from the ideal gas behavior described by the ideal gas law.
non plar gases are ideal gases
The real gas formula used to calculate the behavior of gases under non-ideal conditions is the Van der Waals equation.
Real gases deviate from ideal behavior at high pressures and low temperatures due to interactions between gas molecules. Real gases have non-zero volumes and experience intermolecular forces, unlike ideal gases which have zero volume and do not interact with each other.

The gas molecules interact with one another
The gas which obeyed the gas laws at all conditions of temperature and pressure would be called an ideal gas. They don't actually exist. Real gases obey the gas laws approximately under moderate conditions. Some other points of distinction that can be considered are:Ideal gases are incompressible, non-viscous & non-turbulent.Real gases are compressible, viscous & turbulent.
Boyle's Law applies to ideal gases under constant temperature conditions. It does not apply to real gases or when extreme pressures or temperatures are present, as these conditions can cause gas molecules to deviate from ideal behavior. It is important to consider the limitations of Boyle's Law when dealing with non-ideal gas behavior.
They are two types of Non-Ideal solutions. They are (i) Non-Ideal solutions showing positive deviation (ii) Non-ideal solutions showing negative deviation
Ideal gas law states that there are no inter molecular attractions between gas molecules and that ideal gas does not occupy space therefore having no volume. However, a real gas does have intermolecular attractions and does have a volume.
Ideal gases theoretically have no mass, they are single points. Normally the small size (in comparison to the large space between them) of non-ideal gasses is insignificant, however at low temperatures when kinetic energy and the space between particles is low this mass has significant effects.
