Diffusion Flashcards
1
Q
Why does diffusion happen
A
Because a the random movement of the particles in a gas
2
Q
Diffusion is increased by
A
- temp(kinetic energy)
- concentration (more particles)
- bigger surface area
- shorter distance
3
Q
Net movement
A
Depends on the concentration of the particles on each side of the cell membrane
4
Q
Examples of diffusion
A
- photosynthesis
- respiration
- digestion of food in blood
- oxygen
5
Q
What is diffusion
A
Movement of particles from a high concentration of gas to a low concentration of gas
