Diffusion- hurumanu

Diffusion

intro: What is our focus?
our focus is to learn more about the matter of how to properly define it.


Aim:  investigate if particles diffuse faster in hot or cold water


Hypothesis
I think the hot water will defuse first or make the potassium permanganate spread faster because the hot water makes the particles move faster and the cold water will only make the particles slower.


method
Fill up 2 tetri dishes with hot and cold water
Put each of the Petri dishes with potassium permanganate at the same time.


Particle Theory

1. Particles make up everything
2. Particles are always moving
3. Particles are attached to each other
4. Hotter= faster
5. Colder= slower
6. Always space between particles








Results:
 the hot one did end up going purple faster 


Discussion: I think it happened because when particles are in a hotter environment it tends to move faster than when it is in a colder environment.
