what are we learning in chemicals?
Particle theory is the six rules of particles these are the six rules. these rule help determine how a substance will behave.
- all matter is made up of particles
- all particles in a pure substance are the same
- there is space between all particles
- particles are always moving
- there are attractive forces between particles
- temperature affects the speed at which particles move particles
Diffusion: Is the movement of particles from areas of high concentration to low concentration.
e.g perfume, or like if you add hot water to cold water the water will be hot on one side and cold on the other but over time the hot water will mix with the cold water (in a matter of seconds).
Aim: To observe the effect of temperature on the speed of diffusion.
hypnosis: hot= fast cold=slow
method: we added potassium permanganate to hot and cold water to see how fast the diffusion would happen.
The explanation: the hot water moves the die much faster than the cold one it did this because the particles in the hot water were moving much faster because particle theory rule number six and also because there more heat = energy.
