Particle theory

Today in science we have been learning about particles.......

Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. The particles are held together too strongly to allow movement from place to place but the particles do vibrate about their position in the structure.

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

Today in our experiment we used cold and warm water and we put this type of liquid in both of them to see what would happen in each one of them... it had spread out quicker from in the warm water.
