Select all that apply. an ideal gas does not exist perfectly obeys all gas laws only exists at very low temperatures only exists at very high pressures

does not exist.

perfectly obeys all gas laws.

Explanation:

An ideal gas is the one which obeys all the ideal gas laws. There are some assumptions of ideal gas laws which are mentioned as under:

(1) There are no interactions (attractive/repulsive) at all among the particles of a gas.

(2) Collision of ideal gas particles among each other are elastic. Elastic collision is a kind of collision in which kinetic energy is conserved i.e. loss of total kinetic energy is nil.

(3) Gas particles display rapid, constant & random  motion and the sizes of particles of a gas are extremely small as compared to their distance from each other. In short, we can assume that due the extremely small size of gases their volume is negligible.

But in reality, an ideal gas does not exist in nature because there are some deviations from ideal gas laws which exist in all the real gases at low temperature and high pressure conditions. In such conditions, the particles start interacting with each other and also start occupying finite space.

hey, what do you need . just post the question and i may be able to you : )
