theyre assumed to have zero volume.......
its true always/.//
NO GAS IN UNIVERSE IS IDEAL....
gases such as h2,n2...behave simlar to ideal gas..

If you consider an ideal gas made of nothing but imaginary points in a certain volume, it would theoretically contract to a zero volume at zero K But real gases would become solids before you reached absolute zero. Good example, solid CO2 gas we call "dry ice".

ideal gases have zero volume only at 0 kelvin. PV=nRT
ideal gases is an approximation they don't really exist

no it is not true always bcoz no gas is perfactly ideal. The molecules of ideal gas is negligebly small in comparision to total volume of gas and there are no attractive forces amongst the molecule of ideal gas. The total internal energy of an ideal gas is the kinetic energy of its molecules which depend only on the temperature of the gas means it does not depend on its pressure and volume.
eg:- hydrogen, helium.

An ideal gas is composed of non-interacting points. You would then need a monatomic gas that was of very small size and not polarizable, hence helium near ambient conditions or hot neutral hydrogen plasma in the sun's core.

an ideal gas at STP has a volume of 22.4L
an ideal gas abides by the ideal gas law PV=nRT where the temperature and pressure remains constant

The molecules or atoms are assumed to have zero volume according to the Kinetic Theory.

remember that we don't have real gases in nature.. But you can assume dilute gases(with low pressure) at high temperatures (high enough to avoid intermolecular interactions) as ideal gases...
Rare gases because of their low interactions (only Van der wals forces) can be treated as ideal gases at fairly high temperatures....
