The States of Matter Mod.H U.1 L.5

What is the Matter? States of matter – Physical forms in which matter can exist All Matter – made up of tiny particles – atoms, molecules, ions(charged atoms)

State is determined by… Motion of particles Speed of particles Energy content Amount of attractive forces between particles

The Kinetic Theory All matter is made up of particles All particles are in constant, random motion Go to: http://en.wikipedia.org/wiki/Kinetic_theory#mediaviewer/File:Translational_motion.gif

4 Common States of Matter 2 more, not so common Solid Liquid Gas Plasma ……………………………………………………………………………………. Bose-Einstein Condensate Fermi Condensate

Solids - Properties Has definite shape Has definite volume Particles very close to each other Very strong attraction between particle Particles vibrate in place

1. Solids - 2 Categories: 1. Crystalline Orderly 3-dimensional arrangement of particles in rows - e.g. salt, ice, diamonds

2nd type … Amorphous – Particles in no particular order or pattern -e.g. wax, rubber, glass http://www.edinformatics.com/interactive_molecules/graphite.htm

2. Liquids -Properties Have no definite shape Has definite volume Particles close to each other No definite arrangement Weaker attraction between particles, than in solids Particles move around

2. Liquids- 2 important properties: Surface tension – A Force….

2. Viscosity – A liquid’s resistance to flow. Which flows faster 2. Viscosity – A liquid’s resistance to flow. Which flows faster? Honey, water, syrup?

Liquids are compressible (Slightly) Due to more space between the particles Liquids are used in hydraulic brakes. http://auto.howstuffworks.com/auto-parts/brakes/brake-types/brake1.htm

3. Gases Also fluids Has no definite shape Has no definite volume Particles far apart from each other Weak forces of attraction between particles Particles possess more energy Particles move around freely

4. Plasma No definite shape No definite volume Particles are broken apart or ionized Gases at very high temperature e.g. lightening, fire, the stars, aurora borealis, florescent bulbs, plasma ball http://youtu.be/8nR24XqGSGE 
