Diffusion

Question 1

What is diffusion?

Answer 1

The random mixing and colliding of particles until they are evenly spread out

Question 2

What does the rate of diffusion depend on?

Answer 2

1. The mass of particles. The lower the mass, the faster it diffuses
2. Temperature. The higher the T, the faster it diffuses due to the increase in E provided

Question 3

What does diffusion occur the fastest in and why?

Answer 3

A vacuum as there are no air particles to collide with, slowing them down

Question 4

Describe the kMnO4 crystal experiment?

Answer 4

Add 2 crystals to two different beakers. For one beaker add cold water, for the other add hot water
