Diffusion Flashcards
(4 cards)
1
Q
What is diffusion?
A
The random mixing and colliding of particles until they are evenly spread out
2
Q
What does the rate of diffusion depend on?
A
- The mass of particles. The lower the mass, the faster it diffuses
- Temperature. The higher the T, the faster it diffuses due to the increase in E provided
3
Q
What does diffusion occur the fastest in and why?
A
A vacuum as there are no air particles to collide with, slowing them down
4
Q
Describe the kMnO4 crystal experiment?
A
Add 2 crystals to two different beakers. For one beaker add cold water, for the other add hot water
