Diffusion - Hurumanu 3

What is our focus this week? Our focus is to learn more about matter or how to properly define Diffusion...

Aim: Investigate if particles diffuse faster in hot or cold water.

Hypothesis: I think... I think that the hot water will diffuse or make the Potassium Permanganate will spread faster in the hot water...
Because the hot water would make the particles move faster than the cold water.

Method: Fill up 2 Petri dishes with water, one hot one cold then drop potassium permanganate in both of the Petri dishes, then wait for your result-( Do Not Stir).

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 dish with the hot water spread more because of how fast the particles where moving...

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

  1. Hi Niko! Where is your definition of diffusion? you wrote about how you were learning to define diffusion but didn't tell us what it was....
    It was great to see a discussion to explain your results! What causes the particles to move faster?
