Diffusion Flashcards
1
Q
What is diffusion?
A
Diffusion is the spreading out of particles, resulting in a net movement, from an area of higher concentration to an area of lower concentration.
2
Q
What states of matter can diffusion occur in and why?
A
Gases and liquids because particles can move about randomly.
3
Q
What can increase diffusion rate?
A
Concentration gradient- When there’s a larger difference in concentration.
Temperature- When the temperature is high, because particles can move around faster.
Surface area- When there’s a larger area, more particles can diffuse through at a time.
4
Q
How do specific particles get through the cell membrane?
A
They diffuse. However, if a particle or molecule is too big, it won’t fit.
