Transcript

  • 1. Chemistry is the study of matter and thechanges it undergoes
  • 2. Matter• Anything that has mass and takes up space – Mass is a measure that reflects the amount of matter• Weight is a measure of the amount of matter the also the effects of Earths gravitational pull on that matter• Mass is a way to measure matter independently of gravitational force
  • 3. What can you observe about the arm below?
  • 4. Now what can you observe about the same arm?
  • 5. Structure of Matter• Much of matter is Macroscopic, that which we can observe with our own eyes• Matter can be broken down into smaller pieces (ex. Elements, Atoms)• All that we observe about matter is due to changes that the atoms undergo• Chemistry is the explanation of the submicroscopic events that lead to macroscopic changes• Scientists use models to represent things that are hard to visualize
  • 6. Types of Chemistry• Organic-most carbon containing chemicals• Inorganic-matter that does not contain carbon• Physical- the behavior and changes of matter and the related energy changes• Analytical-components and composition of substances• Biochemistry-matter and processes of living organisms• Environmental-matter and the environment• Industrial-chemical processes in industry• Polymer-polymers and plastics• Theoretical-chemical interactions• Thermochemistry-heat involved in chemical processes
  • 7. Exit Notes• Section 1.2 Assessment, Ques. 9• Summarize why it is important for chemists to study changes in the world at a subatomic level
