  1. Luku 1 Kemia on luonnontiede, joka tutkii aineiden kemiallisia ominaisuuksia, rakenteita ja reaktioita, joissa aineet muuttuvat toisiksi aineiksi.

  2. Olomuodot

  3. Crystalline Solids • some solids have their particles arranged in an orderly geometric pattern – we call these crystalline solids • salt and diamonds

  4. Amorphous Solids • some solids have their particles randomly distributed without any long-range pattern – we call these amorphous solids • plastic • glass • charcoal

  5. kaasu->neste tiivistyminen(condensation) • neste->kaasu höyrystyminen(vaporization • neste->kiinteä jähmettyminen(freezing) • kiinteä->neste sulaminen(melting, fusion) • kiinteä->kaasu sublimoituminen(sublimation) • kaasu->kiinteä härmistyminen(deposition)

  6. Puhtaat aineet

  7. Different Physical Property Technique Boiling Point Distillation State of Matter (solid/liquid/gas) Filtration Adherence to a Surface Chromatography Volatility Evaporation Density Centrifugation & Decanting
