  2. State (or phase) of Matter • The physical form in which matter exists • Four states • Solid • Liquid Most common on Earth • Gas • Plasma

  3. SOLIDS • Have a definite shape and volume • How do we find the volume of a solid? • Length x Width x Height

  4. Liquids • Has a definite volume. • How do we find a liquid’s volume? • What is a liquid’s shape? • It takes the shape of its’ container • No definite shape

  5. Gases • No definite shape or volume • Takes the shape of its’ container • Gas molecules will spread out to occupy all of the space available.

  6. PLASMA • Also no definite shape or volume. • Forms when temperatures are high enough to remove electrons from their atoms • When an atom loses electrons, it becomes a positively charged ion.

  7. Particles and Phase • The arrangement and motion of the particle that make up a substance determine its state.

  8. SOLIDS • Particles are packed together quite closely • The energy bonding these particles is very strong • This prevents particles from moving freely • Particles move by vibrating in their position • Gives solids their definite shape and volume

  9. Liquids • Particles are less densly packed than those in a solid • Energy bonding particles is weaker than in a solid • Particles can move around and slide past one another • Movement of particles prevents liquids from having a definite shape

  10. Gases • Particles move freely • Allows gases to expend and contract to fit its container • Thus gases lack shape and volume • Energy binding the particles is weak

  11. Plasma • Particles move fast • Plasma is different from a gas, because it’s made up of groups of positively and negatively charged particles. • Energy binding the particles is very weak

  12. Particle Arrangement

  13. Heat Affects the State of a Substance • When a substance takes in heat, its particles gain energy and move more quickly • When a substance releases heat, its particles lose energy and move more slowly.

  14. When enough heat is added or removed, a change of state occurs. LIQUID • Solid + Heat = • Liquid + Heat = • Gas – Heat = • Liquid – Heat = GAS LIQUID SOLID

  15. Solid + Heat = Liquid • Melting point: the temperature at which a solid begins to change to a liquid.

  16. Liquid + Heat = Gas • Vaporization • The process in which a liquid changes to a gas • Boiling Point • The temperature at which a liquid changes to a gas

  17. Gas – Heat = Liquid • Condensation • The changing of a substance from a gas to a liquid • The temperature is the same as the substance's boiling point, it’s just going in the opposite direction.
