Non-steady state diffusion occurs when there is a change in concentration over time in a system.

Can diffusion and osmosis occur simultaneously?

Yes, diffusion and osmosis can occur simultaneously. Diffusion is the movement of molecules from an area of high concentration to low concentration, while osmosis specifically refers to the movement of water across a selectively permeable membrane. In a system with solutes and a semi-permeable membrane, both processes can happen at the same time.


Would you expect diffusion to occur more or less rapidly at a higher temperature?

Diffusion would occur more rapidly at a higher temperature. This is because higher temperatures increase kinetic energy of molecules, causing them to move faster and spread out more quickly.


What is the difffrence between diffusion and osmosis?

1 diff. Semi permiable membrane is required in osmosis while it is not required in diffusion. 2 diff. Osmosis cn occur only in liquid medium while diffusion cn occur in all mediums.


Why does diffusion occur and does it always occur?

All Particles move using their kinetic energy. Diffusion occurs because of difference in concentrations. The higher the concentration gradient the faster the diffusion rate. When diffusion happens it mixes both concentrations to obtain an equal concentrations meaning equilibrium has been reached. However, particles still move about from one section to the other, so to be more specific we say that dynamic equilibrium has been reached.


What natural phenomenon allows diffusion to occur?

The natural phenomenon that allows diffusion to occur is the tendency of particles (atoms, molecules, ions) to move from areas of higher concentration to areas of lower concentration in order to reach equilibrium. This process is driven by the principle of entropy, which favors the distribution of particles to be as uniform as possible.
