Diffusion is the process by which molecules of a gas move from a more concentrated state to a less concentrated state because they are constantly in motion. All gases are constantly in motion and this is the basis of the kinetic molecular theory. You may experience this when someone standing near you uses perfume or a spray cologne and you quickly detect the odor of the perfume.
Three examples that come to mind are first the detection of leaks of natural gas when you smell the odorant that is added to natural gas. Natural gas has no odor of its own and so a strongly smelling sulfur compound is added. This way if a leak occurs it can be quickly detected and fixed, minimizing the possibility of an explosion.
A second example would be the release of oxygen from plants during photosynthesis. This oxygen is necessary for all animal life on earth and if it did not quickly diffuse some areas of the world would have high levels of oxygen while other areas (such as deserts) would have almost none.
A third example is the exhaust from automobiles. This exhaust contains, along with carbon dioxide and water, many other compounds, some of which are harmful and even potentially fatal, to people. Because of diffusion, the gases in the exhaust quickly mix with the surrounding air and drop to levels that are no longer dangerous to us.
Gases spread quickly because it has more pleetah in it so it spreads vastly
Due to less intramolecular attractions and also due to high intermolecular spaces
The coefficients of diffusion are greater and the intermolecular strength is lower.
Liquids and gases are amorphous (shapeless), viscous (can flow), and diffuse (have internal space) due to the movement of their molecules.
diffusion is dependent on chemical reactivity (can't diffuse if you're in a bond) and mass. So the lightest most un-reactive gases will diffuse the quickest. Helium would seem to be the best contender. diffusion is dependent on chemical reactivity (can't diffuse if you're in a bond) and mass.

gas matter's characteristics is GAS
The molecules of a gas move faster at higher temperatures, which therefore speeds up diffusion.
They have capillaries close to their surfaces.
Gases have more energy than liquids so they expand more quickly
oxygen and carbon dioxide
Diffusion of gases easily occurs across a membrane. The gases will have to be converted into liquids so as to diffuse easily.
All gases diffuse to a homogenous phase.
gases with the higher molar mass
what is the procedure to diffuse two gases show the result
Smaller molecules diffuse readily.
Its down to the molecules in the substance, in gases they are not that close to each other so they can move around quicker and faster so hence diffuse quicker in solids or most they are that tight they can not move are as easily.
I had to find the answer to the question too. I think it is to allow gases to diffuse around the cells. It is too important for the gases oxygen when respiring and carbon dioxide when photosynthesis and water during transpiration
