Particle Theory

Hi Guys

Particle Theory


Lately in chemicals we have been learning about matter and now they work also how particles work and something called particle theory.


There is six rules in particle theory and they are:
All mater 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.

Diffusion: Movement of particles from high concentration to low concentration. eg. Deodorant
Rules that go with them: Particles are always moving, Temperature affect the speed at which particles move,There is space between all particles.

Aim: We tested how quick the affects of temperature has on speed of diffusion.
Hypothesis: the heat will make it spread fast and the cold will be slow.
Method: put potassium permanganate in hot and cold water and sees what spreads faster.
Observation and explanation: The hot water made potassium permanganate spread the fastest.


BYE!
