Ideal gases can be condensed, but the ideal gas model may fail for gases at higher temperatures.
There are ideal gases..
An ideal gas cannot be condensed because it is assumed that ideal gas particles have no intermolecular forces and occupy no volume. This means that, under ideal conditions, they do not attract each other, which prevents them from coming together to form a liquid or solid state. Additionally, the kinetic energy of the particles is assumed to be sufficiently high to overcome any potential attractive forces that might lead to condensation.
When a gas is changed to a liquid the gas has condensed, or liquefied or cooled.

the ideal gas constant D:
Krypton is not an ideal gas because it deviates from the ideal gas law at high pressures and low temperatures due to its intermolecular interactions. At standard conditions, krypton behaves closely to an ideal gas, but as conditions vary, its non-ideal characteristics become more pronounced.
A model for the solar system in which the sun and planets condensed from a cloud (or nebula) of gas and dust
you cant do it
No, CO2 is not considered an ideal gas because it does not perfectly follow the ideal gas law at all temperatures and pressures.
No, oxygen is not considered an ideal gas because it does not perfectly follow the ideal gas law at all temperatures and pressures.
All gas laws are absolutely accurate only for an ideal gas.
In an ideal gas molecules interact only elastically.
