Why does gas occupy more space?

Gases take up a lot of space because they lack inter-molecular forces.

Do real gases occupy space?

While it does approach a small number, it will not be zero because molecules do occupy space (i.e. have volume) and cannot be compressed. (2) Intermolecular forces do exist in gases.

Do ideal gases have zero volume?

An ideal gas would have zero volume. But IRL there is no “ideal gas”. The higher the pressure and lower the temperature, the further from ideal behavior you get with any gas. And those two conditions (high P, low T) are what would be required to reduce the volume of a gas to or near zero.

Why does matter occupy space?

Matter is anything that has mass and takes up space. Mass gives an object the property of weight and inertia (resistance to change in the motion of an object). If something is in a solid state of matter, it has a definite shape and volume. The volume of an object is the amount of space it occupies.

Why do real gases deviate from ideal gases?

Gases deviate from the ideal gas behaviour because their molecules have forces of attraction between them. At high pressure the molecules of gases are very close to each other so the molecular interactions start operating and these molecules do not strike the walls of the container with full impact.

Why real gas shows deviation from ideal gas?

While the particles of an ideal gas are assumed to occupy no volume and experience no interparticle attractions, the particles of a real gas do have finite volumes and do attract one another. As a result, real gases are often observed to deviate from ideal behavior.

What happens when an ideal gas reaches 0 Kelvin?

At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale.
