Diffusion Flashcards
1
Q
What is diffusion?
A
The net movement of particles of an area of high concentration to an area of low concentration.
2
Q
What is an example of diffusion in the body?
A
Urea is a waste product that moves into the blood plasma.
3
Q
How does surface area speed up diffusion?
A
More can go in and out.
4
Q
How does a smaller concentration gradient affect diffusion?
A
It allows more molecules to diffuse.
5
Q
How does a thin diffusion area affect diffusion?
A
Less distance=faster diffusion
6
Q
How does temperature affect diffusion?
A
With more kinetic energy they move faster by diffusion.
7
Q
What is kinetic energy?
A
Energy store of movement.
