Usually in a gas, the distance between molecules is larger.
Air molecules are much bigger than helium molecules.
Well, "air" isn't a molecule. Air is considered oxygen. Oxygen molecules are very, very, very small. Microscopic.
Size ~ Distance/1,000,000,000
As air pressure in an area increases, the density of the gas particles in that area decreases.
It is a decrease.
High temperature and low pressure. High temperature because this speeds up the rate of the molecules so there is less intermolecular forces of attraction between particles. Low pressure because the greater the distance of the particles and the less molecular forces of attraction between particles.
Usually yes, but the distance between the particles depends on pressure. A gas at high pressure can actually have particles fairly close together.
Chemical nitrogen 1 it is pure as it does not have any inert gases. 2 it is lighter compared to atmospheric nitrogen. 3 it is highly reactive. Atmospheric nitrogen 1 it has 1% inert gases. 2 it is heavier than chemical nitrogen due to the dust particles. 3 it is less reactive because of the inert gases.

-- The product of the electric charges on both particles.-- The distance between the centers of charge on both particles.-- The electrostatic permittivity of the space between themor of the substance in that space.
the distance between the particles and the average kinetic movement of the particles.
Attractive forces pull particles together.

The electric force between two charged particles is inversely proportional to the square distance between them.Accordingly, it is reduced by a factor of 9

As air pressure in an area increases, the density of the gas particles in that area decreases.
It is a decrease.
Particles are always in motion because they have an amount of heat energy stored within them. As additional heat is added, the substance's particles gain more energy, and will in turn increase distance between themselves, and weaken the bonds between them. In turn, when heat is taken away from a substance (it is cooled down) the particles loose energy, and the distance between them will decrease, causing the bonds between them to strengthen. The whole idea is known as the particle theory. However, particles may not be always in motion. Scientists discovered the temperature point of absolute zero, which is -273.15°C, or 0°K (Kelvin). This is the lowest temperature possible.
