Particle Theory

Today we have been learning about the Particle Theory in chemicals 

Particles in a solid have no space and vibrate. Particles in a liquid have no shape but volume. Particles in a gas have no shape and no volume.

and here are the six rules of the Particle Theory

• 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

Diffusion: movement of particles from high concentration to low concentration. So the temperature affects the speed of particles.

eg: Smelly feet for warm heat and cold = non-smelly feet

Science experiment

My hypothesis is that the Potassium permanganate will spread in warm water faster than the cold water because it makes the particles fast while the cold water makes it slower.

Potassium permanganate in cold water it spreads slow and in warm water, it was faster than the cold water because the hot temperature makes is so that the particles go faster.
