Diffusion Flashcards
1
Q
what is diffusion
A
spreading out of particles from a high to low concentration
2
Q
how does surface area affect diffusion
A
the larger it is, the faster the diffusion rate
3
Q
what happens when the temp is raised
A
the higher it is ,the rate of diffusion will be higher
4
Q
how does the concentration gradient affect diffusion?
A
the steeper it is the faster the rate of diffusion
5
Q
what is a concentration gradient?
A
a measurement of how the concentration of something changes from one place to another
6
Q
how does the diffusion pathway affect diffusion?
A
the shorter it is the quicker diffusion will be
7
Q
what type of process is diffusion
A
passive
8
Q
what is a passive process
A
passive process which means it does not require energy
