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 e.g fast-moving particles are hot and vice versa

Diffusion: Is the movement of particles from areas of high concentration to low concentration.

e.g perfume, or like if you add CO2 and O2 (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 at the same time 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 of particle theory rule number six and also because there more heat = energy.
