  1. Chemistry 100 • Understand the scientific method • Define and give examples of 3 states of matter • Distinguish between substances, mixtures, • Understand and be able to apply the different separation techniques Instructor: Mark Davis

  2. What is Chemistry? • The study of all substances • The CENTRAL SCIENCE

  3. Why Study Chemistry? • Useful for other sciences • Required course  • Fun and Challenging • Remember: • Process of Discovery • Understand Concepts, NOT Single Facts

  4. Scientific Method Observation Question Experiment Conclusion

  5. Scientific Method Conclusion • Theory • Explains why nature behaves in a certain way • Natural Law • Explains how nature behaves Prediction Experiment

  6. What is Matter? • Anything that has • Composed • Exists in three states on earth • Exists in fourth state in space

  7. Solids • Definite • Particles • Crystalline – • Amorphous solids –

  8. Liquids • Definite • Not a • (Takes shape of container) • Particles have • Particles can

  9. Gases • Indefinite • No definite • Particles have • Particles move

  10. States of matter animation • http://www.harcourtschool.com/activity/states_of_matter/

  11. Substances and Mixtures • Pure Substance: • Mixture: • Not

  12. Pure Substances • Elements • Compound

  13. Matter Pure substances (homogeneous composition) Mixtures of two or more substances Elements Compounds Solutions (homogeneous composition – one phase) Heterogeneous mixtures (two or more phases) Figure 3.2 (page 48)

  14. Types of Mixtures • Heterogeneous mixtures • Visibly • Two or more • Homogeneous mixtures • Different

  15. Separating Mixtures • Do NOT cause

  16. Separating Mixtures • Homogeneous

  17. Separating Mixtures

  18. Separating Mixtures
