The ideal gas law assumes gases are composed of non-interacting point particles, whereas real gases have interactions between molecules that affect their behavior. Real gases deviate from ideal behavior at high pressures and low temperatures, causing them to have different properties such as compressibility factors. These interactions are accounted for using empirical corrections like the van der Waals equation.

Why Real gases do not obey gas laws?
Real gases do not perfectly obey gas laws because they have volume and exhibit intermolecular forces, which are not accounted for in ideal gas law equations. Real gases can deviate from ideal behavior at high pressures and low temperatures when the volume of the gas particles themselves and the attractive forces between particles become significant.
Do real gases follow the ideal gas equation?
No, real gases do not always follow the ideal gas equation. This is because real gases have volume and interactions between gas molecules that cause deviations from ideal gas behavior under certain conditions, such as high pressures or low temperatures. The ideal gas equation assumes no volume and no intermolecular forces between gas particles, which is not always the case for real gases.
In an ideal gas compared to a real gas at very high pressure occupies?
In an ideal gas compared to a real gas at very high pressure, the volume occupied by the real gas will be smaller than predicted by the ideal gas law. This is because real gases experience intermolecular forces that cause them to be less compressible than ideal gases at high pressures.
Ideal gas law behavior of real gases under?
Real gases deviate from ideal gas behavior at high pressures and low temperatures due to interactions between gas molecules. These interactions cause deviations in volume and pressure from what would be expected based on the ideal gas law. At very high pressures or very low temperatures, these deviations become significant and the ideal gas law no longer accurately describes the system.
When do real gases act least like ideal gases?
Real gases act least like ideal gases under conditions of high pressure and low temperature, where the gas molecules are closer together and experience intermolecular forces that are not accounted for in the ideal gas law.
What are real and ideal gases and are all real gases ideal?
Real gases are gases that do not perfectly follow the ideal gas law due to intermolecular interactions, volume occupied by gas molecules, and pressure. Ideal gases are imaginary gases that perfectly follow the ideal gas law at all conditions. Not all real gases are ideal; ideal gases are a theoretical concept that simplifies the behavior of gases under certain conditions.
How does an ideal gas diff from a real gas?
An ideal gas follows the ideal gas law exactly, while a real gas may deviate from the ideal gas law at high pressures and low temperatures due to intermolecular forces and molecular volume. Real gases have non-zero molecular volume and experience intermolecular interactions, while ideal gases are assumed to have no volume and no intermolecular forces.
What is an imaginary gas that conforms perfectly to the kinetic molecular theory callled?
An imaginary gas that conforms perfectly to the kinetic molecular theory is called an ideal gas. Ideal gases have particles with no volume and no intermolecular forces between them, allowing them to perfectly follow the assumptions of the kinetic molecular theory.

No, real gases do not always follow the ideal gas equation.

The ideal gas equation assumes no volume and no intermolecular forces between gas particles, which is not always the case for real gases.
How can a real gas be made to approach being an ideal gas?
A real gas can approach being an ideal gas by decreasing its pressure and increasing its temperature. At low pressures or high temperatures, the interactions between gas molecules become less significant, causing the gas to behave more like an ideal gas. Additionally, using larger volumes can also help minimize intermolecular interactions and make a real gas behave more like an ideal gas.
Why is the ideal gas law useful even though gases do not exist?
The ideal gas law is useful as an approximation for real gases in many situations where the gas behaves similarly to an ideal gas. It helps chemists and physicists predict the behavior of gases under different conditions without having to account for all the complexities of real gas behavior. While gases may not perfectly follow the ideal gas law, it provides a good starting point for understanding gas behavior.
What are two characteristics of an ideal gas that are not true of a real gas?
Ideal gases do not have intermolecular forces or occupy volume, while real gases do have intermolecular forces and occupy space.
Why real gases deaviat from ideal behaviou?
It is assumed that Ideal Gases have negligible intermolecular forces and that the molecules' actualphysical volume is negligible. Real Gases have the molecules closer together so that intermolecular forces and molecules' physical volumes are no longer negligible. High pressures and low temperatures tend to produce deviation from Ideal Gas Law and Ideal Gas behavior.
In an ideal gas compared to a real gas at very high pressure occupies?
In an ideal gas compared to a real gas at very high pressure, the volume occupied by the real gas will be smaller than predicted by the ideal gas law. This is because real gases experience intermolecular forces that cause them to be less compressible than ideal gases at high pressures.
Why cant a gas be an ideal gas?
There are ideal gases..
Ideal gas law behavior of real gases under?
Real gases deviate from ideal gas behavior at high pressures and low temperatures due to interactions between gas molecules. These interactions cause deviations in volume and pressure from what would be expected based on the ideal gas law. At very high pressures or very low temperatures, these deviations become significant and the ideal gas law no longer accurately describes the system.
