Properties of Materials – Part B

Unit Objectives: By the end of this unit (Part B), you should be able to:

Describe the history of materials,
Use the kinetic (particle) theory to explain changes of state in matter,
Trace the flow of heat during changes of state and chemical changes,
Distinguish between elements, compounds, homogeneous and heterogeneous mixtures,
Describe matter and its changes in terms of microscopic and macroscopic properties,
Distinguish among physical, chemical, thermal, electrical, optical and mechanical properties,
Use these properties to identify a substance, and
Recognize that some materials exhibit unusual properties—outside of conventional definitions.
