Diffusion happens because particles in gases and liquids move about. However diffusion would be greater in gas than in liquid because the particles in a gas move and spread quicker and there is more space to move to.

When gases mix, their individual molecules start colliding with each other. As they collide, they go in random directions, some of them deeper into the other gas, which causes more collisions. As these collisions continue, the gases become more intermixed, or diffused.

Butane, for example, has only weak dispersion forces(very weak positive and negative areas). Thus, butane molecules don't stick together very well so they spread out in space as much as possible. Molecules with stronger forces(stronger positive and negative areas) holding their molecules together, water for example, need a lot of heat before they can overcome those forces and spread out.

True.


Why does diffusion happen when gases are mixed?

diffusion happen because of the motion of the gas particle which they are travelling faster than the particles in solid and liquid and the different atomic mass of the gases


What is the process when two gases slowly mix?

This process is called gas diffusion.


When and where does diffusion happen?

diffusion can happen either in gases or liquids. it happens when a high concentration of something appears and it spreads out until an equilibrium is reached.


Can diffusion mix?

Of course, especially liquids and gases, but even solids, especially at high temperature


When two gases are mixed what is it called?

A process of gas diffusion occur and a mixture of gases is obtained.


Does diffusion happen best in liquids?

The rate of diffusion is fastest is gasses, but as we can't see the gases ,it can be seen it liquids, but in liquids the rate of diffusion is comparatively slower than gasses and it can be easily observed....


What will happen when two different gases at different pressure mixes in a single pipe?

The pressure will equalise and the two gases will mix.


Do gases show the property of diffusion?

Yes, gases do show the property of diffusion as its molecules are loosely packed.


How does gases enter and leave capillaries?

Simple diffusion.


What will happen by process of diffusion?

Diffusion is when the molecules of spread out to where there is less of it until it's equal. Think and watch of what happens the next time you make lemonade with powdered mix.


Why rate of diffusion in liquid is slower than in gases?

The rate of diffusion in liquids slower than that of gases because gases have low density and its float in the air.
