How are molecules distributed in the environment As explained in this animation the random movement of molecules in a gas or a liquid will cause the molecules to become evenly distributed in the environment. If we look at the environments in which cells exist for example inside a body or in a pond we do not see an even distribution of molecules associated with life. Cells prevent control

What keeps the different gases mixed in the atmosphere

If you separate two gases of different densities by a horizontal membrane and then slowly remove the membrane then the interface will diffuse. You can try this with bromine and air for examplethe bromine will stay at the bottom (easily visible because it s brown) and the air will stay at the top but the interface will be diffuse.

What Effect Does Temperature Have on the Process of Diffusion

If two different gases or liquids are close to each other the process of diffusion causes them to mix together. Imagine two gases separated by a partition. The free-moving gas molecules bounce off the central partition as they whirl around in their container. If the partition is removed the gases mix as the molecules move around.
