Diffusion Flashcards
What states of matter can diffusion happen in and why?
Liquids and gases because the particles are free to move about
What is diffusion?
The spreading out of particles from an area of high concentration to an area of low concentration
What make the rate of diffusion faster?
A bigger difference in concentration
Can diffusion happen in cells?
Yes
How does diffusion happen in cells?
Cells have a cell membrane which lets very small molecules in and out
Why can’t starch and proteins be diffused into cells?
They’re too big
When is there a net movement of particles?
When there is more particles on one side of the membrane
What is the simplest form of diffusion?
When gases diffuse through each other, for example in the air
