For ideal gas force of attraction between molecules?
In an ideal gas there is no attarcation between molecules. There is no such thing as an ideal gas it is a model that approximates the behaviour of real gases.
Would a gas whose molecules were true geometric points obey the ideal gas law?
If gas molecules were true geometric points (ie had zero volume) AND had zero intermolecular interaction (such as attraction or repulsion), then the gas would obey the ideal gas law. Gases composed of small, non-interactive molecules (such as helium gas) obey the ideal gas law pretty well (as long as the gas is low density and temperature is rather high). For non-ideal gases, at least two correction factors are often used to modify the ideal gas law (correcting for non-zero volume of gas molecule and intermolecular attraction) such as in the Van der Waals equation for a real gas.
What describes a gas on the microscale?
A gas contain very dispersed molecules.
How does the ideal gas law relate to real gases?
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.
Is ideal gas one whose particles take up space?
An ideal gas is a theoritical gas consisting of randomly moving particles.The kinetic theory of ideal gases makes 5 main assumptions:The size of molecules is negligible compared with the mean intermolecular distance (i.e. they are widely spaced molecules).Molecules move with different speeds and in random directions.Standard laws of motion apply.Collisions between molecules are elastic. Translational kinetic energy is not converted into other forms of energy.There are no attractive intermolecular forces between molecules except during collision.

Diff between real gas and ideal gas?
In an ideal gas molecules interact only elastically.
Explain what is the difference between real gas molecules and ideal gas molecules by kinetic theory?
In an ideal gas, molecules don't take up space, and don't have long-range interactions.

What happenes to the particels of a gas when there are fewer of them?
This is the ideal gas with no collisions between molecules..
What makes a gas non-ideal?
The gas molecules interact with one another
When can you safely assume any gas is ideal?
Characteristics of an ideal gas:- an extremely low concentration- molecules are in a permanent motion- Newton laws can be applied- all collisions are elastic- molecules are spherical- molecules are not compressible
A real gas differs from an ideal gas because the molecules of real gas have?
The molecules of real gas have some volume and some attraction for each other.

What would make gas non ideal?
The gas molecules interact with one another
What characteristic makes a gas non-ideal?
