Three States of Matter

Three States of Matter. First, fold your paper in half like this. Not this. You need three “flaps.”. To cut “flaps,” cut only the top half of the folded paper. 1. 2. 3. Do not write these numbers on your flaps!. There are three states of matter. Gas. Liquid. Solids.

  1. Three States of Matter

  2. First, fold your paper in half like this. Not this.

  3. You need three “flaps.” To cut “flaps,” cut only the top half of the folded paper. 1 2 3 Do not write these numbers on your flaps!

  4. There are three states of matter Gas Liquid Solids • Constant motion • Kinetic Energy • Particles are far apart • Move freely-particles are not attracted to each other • Constant motion • Particles are packed close together • Move around a fixed point • Constant Motion • Particles close to each other • Free to move, but are attracted to each other • Not rigid or orderly

  5. There are three states of matter Gas Liquid Solids • Constant motion • Kinetic Energy • Particles are far apart • Move freely-particles are not attracted to each other • Constant motion • Particles are packed close together • Move around a fixed point • Constant Motion • Particles close to each other • Free to move, but are attracted to each other • Not rigid or orderly

  6. 3 2 1 Inside flap 1 – Gas • Characteristics • Compressible • Take shape of their container • Expand to fill volume of container • Free to flow Vapor-gas from the surface of a liquid or solid

  7. 3 2 1 Inside flap 1 • Element gas: • He • Oxygen, O2 • Nitrogen, N2 • Chlorine, Cl2 • Compounds: CO2, H2O, NO2

  8. Characteristics Do not Compress Take shape of their container Fixed volume Free to flow Expand slightly when heated 3 2 1 Inside flap 2 – Liquids

  9. 3 2 1 Inside flap 2 • There are many of liquids! • Compound examples: • H2O, H2O2 (Pure Liquid) • Br2 only non-metal liquid element at RT • Gasoline (mixture of liquids) • Hg –only metal liquid element at RT

  10. Characteristics Do not Compress Fixed volume Definite Shape Expand very, very slightly when heated 3 2 1 Inside flap 3 – Solids

  11. 3 2 1 Nanoscale • Millions of examples of Solids! • Compounds: NaCl, C12H 22 O11 • Element: Au, Ag,Cu,K…. • Mixtures: Fe/C Steel • Alloy mixture of element solids
