Diffusion Flashcards
1
Q
What is diffusion?
A
The movement of particles from a place of higher to lower concentration.
Able to happen in gasses and liquids but not solids
Passive process, no energy is needed
2
Q
What are the factors affecting diffusion?
A
Concentration gradient
Temperature
The distance particles must travel
Large surface areas
3
Q
When can faster diffusion occur?
A
Larger concentration
High temperature
Shorter distances for particles to travel
Large Surface Area/Volume ratio
4
Q
For diffusion Is there...? Energy required Membrane Other factors needed
A
No energy is required
No membrane is required
Nothing is required
