what is the distance between gas particles?
148782
Gases consist of very large numbers of tiny spherical particles that are far apart from one another compared to their size . The particles of a gas may be either atoms or molecules. The distance between the particles of a gas is much, much greater than the distances between the particles of a liquid or a solid.

Nanoparticles. Nanoparticles are structures, 1-100 nanometres (nm) in size, that usually contain only a few hundred atoms . This means that nanoparticles are around 100 times larger than atoms and simple molecules . 1 nm is 1 x 10 -9 m (or 0.000,000,001 m).

Each particle (surrounded by water) becomes a tiny droplet between 0.0001 and 0.005 centimeter in diameter. (The particles range in size, therefore, the droplets range in size.) ... If it gets any larger than 4 millimeters, however, it will usually split into two separate drops.

So the average speed of a gas molecule is about 500 m/sec. This is roughly the speed of sound in a gas 340 m/sec. So the average kinetic energy of the gas molecules is related to the temperature of the gas.

Why do solids have an open surface area whereas gases do not have? Accepted Answer: The particles of solids are very close to each other and force of attraction between the particles is very strong. ... Therefore, gases do not have definite shape, they diffuse easily into air and hence have no open surface area.

Gas – In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles.

Mean inter-particle distance (or mean inter-particle separation) is the mean distance between microscopic particles (usually atoms or molecules) in a macroscopic body.

There are 6 x 10^23 particles in one mole of gas. Therefore, in 10,000 moles of air there will be 10,000 x 6 x 10^23 = 6 x 10^27 particles. Avogadro's constant and the amount of space a mole of gas takes up are fixed – so this answer is really dependent on how big your room is.

A mole of a substance or a mole of particles is defined as exactly 6.02214076×1023 particles, which may be atoms, molecules, ions, or electrons. In short, for particles 1 mol = 6.02214076×1023.

A gas usually has much lower density than a solid or liquid. ... The molecules or atoms in a gas are much further apart than in a solid or a liquid. Gas molecules or atoms are usually flying around at very high speeds, occasionally bouncing off each other or the walls of the container the gas is in.

What is the key difference between gases and liquids that sets them apart? The particles in a liquid are attracted to one another; the particles in a gas *are not attracted *.

The theory assumes that collisions between gas molecules and the walls of a container are perfectly elastic, gas particles do not have any volume, and there are no repulsive or attractive forces between molecules. These assumptions pertain to Ideal Gases.

At NTP 22.4 litres of a gas forms one mole that is 6.023×10^23 molecules. Volume of CO2 in 1 litre air= (0.03÷100)×1 litres.

Explanation: Recall that moles can be converted to particles using Avogadro's constant ( 6.022⋅1023 ) which is the number of molecules per mole of a substance. In 1.5 moles of fluorine gas, there are 1.5⋅6.022⋅1023 molecules of gas.

['Gases have neither definite shape nor definite volume. They expand to the size of their container.', 'Gases are fluid, and flow easily.', 'Gases have low density, unless compressed. ... ', 'Gases diffuse (mix and spread out) and effuse (travel through small holes).']

The answer is pretty simple using a little approximation and mole concept. =0.042*10^3 x 6.022 x 10^23 molecules = 2.53 x 10^25 molecules of air.

The Ideal Gas Law does not account for these interactions. At high pressures, gas particles are forced into close proximity with one another, causing significant intermolecular interactions. ... At high pressures and low temperatures, these attractive forces can become significant.
