Sections 1.1-1.6
1.1 - Some Fundamental Definitions
Concepts
- Be able to distinguish between physical and chemical properties and changes
Skills
- Be able to define features that distinguish one state of matter from another (gases, liquids, & solids)
- Assigned Problems 1.3
- Be able to describe the differences between kinetic energy (K.E.) and potential energy (P.E.) and how one can be converted to the other.
- Assigned Problems: 1.8, 1.9, 1.89
1.2 - Chemical Arts and the Origins of Modern Chemistry
Concepts
- Be able to discuss the earlier contributions to chemistry by the Greeks and the alchemists and the experiments of Antoine Lavoisier, which lead to the dawn of modern chemistry.
