Diffusion/Particle theory - Hurumanu 3

Diffusion/Particle theory

This week our focus is about particle theory - and how particles move

Aim- Investigate if particles diffuse faster in hot or cold water

Hypothesis- I think that the particles will diffuse faster in hot water 

Method- fill up 2 petri dishes one hot one cold 

               Add the potassium permanganate  

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 then when it is in a colder environment.
