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.

What properties do liquid and gases have due to the movement of their molecules?
Liquids and gases are amorphous (shapeless), viscous (can flow), and diffuse (have internal space) due to the movement of their molecules.
What gases diffuses most rapidly at stp?
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.

What are the characteristics of gas matter?
gas matter's characteristics is GAS
Why would gases diffuse faster on a warm day than on a cold day?
The molecules of a gas move faster at higher temperatures, which therefore speeds up diffusion.
How did rice diffuse and where did it diffuse to?
my mom
How does alveoli help two gases diffuse quickly into and out of the blood?
They have capillaries close to their surfaces.
Do gas diffuse?
by cooling
Does all gases diffuse the same speed?
No, all gases do not diffuse at the same speed. Factors such as molecular weight, temperature, and pressure influence the diffusion rate of gases. Lighter gases tend to diffuse faster than heavier gases.
What two important gases diffuse across the respiratory membrane?
Oxygen and carbon dioxide are the two important gases that diffuse across the respiratory membrane. Oxygen moves from the alveoli into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.
What are the 6 characteristics of gas?
Gases have no definite shape or volume and expand to fill their container. They are highly compressible and tend to diffuse quickly. Gas particles are in constant, random motion. Gases have low densities compared to liquids and solids. They do not exhibit strong intermolecular forces. Gases are affected by changes in temperature, pressure, and volume.
what are the gases diffuse at lowest rate?
gases with the higher molar mass
Do hydrogen and oxygen diffuse?
Yes, both hydrogen and oxygen are gases at room temperature and pressure, so they can diffuse easily in air. Diffusion is the process by which gases mix due to the random motion of their particles.
Which diffuse faster-liquid or gas and why?
Gases diffuse faster than liquids because gas particles have higher kinetic energy and move more freely compared to the more confined and slower-moving particles in a liquid. This allows gas particles to spread out more quickly and cover a larger area in a given amount of time.
Would liquid bromine diffuse more or less quickly than gaseous bromine after pouring it into another liquid?
Liquid bromine would diffuse more slowly than gaseous bromine when poured into another liquid. Diffusion occurs more readily in gases and in liquids, but since bromine is more dense in its liquid state, it will diffuse at a slower rate compared to when it is in its gaseous state.
Why do gases duffuse quickly but most solids do not?
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.
What procedure is used for diffusion of gases?
what is the procedure to diffuse two gases show the result
Why do gases have the highest rate of diffusion(long answer)?
Gases have the highest rate of diffusion because their particles are widely spaced and move quickly due to their high kinetic energy. This allows gas particles to easily spread out and mix with other substances in their environment. In contrast, liquids and solids have particles that are more tightly packed, which limits their ability to diffuse quickly.
