  1. Chemistry The study of matter

  2. Matter is stuff. • Stuff is found in 4 different states: • Solid • Liquid • Gas • Plasma

  3. Solids • Have a fixed shape and volume • Particles maintain a specific position

  4. Liquids • Have a fixed volume • Take the shape of their container

  5. Gases • Have no fixed shape or volume

  6. Plasma • Like gases, but ions get separated from their electrons

  8. Changing states

  9. Phase changes are physical changes. • In a physical change, you change the shape or size of something, but it is still the same stuff. • In a chemical change, a substance is completely changed.

  11. Phase change math • Specific heat of liquid water = 4.186 joule/gram °C • Specific heat of ice = 2.09 J/g·°C • Specific heat of water vapor = 1.996 J/g°C • Heat of fusion = 334 J/g • Heat of vaporisation = 2260 J/g
