We will be completing a short quiz on Edmodo on Wednesday October 22nd
Study labs 5-7 and their results as well as your reading homework summaries and information to prepare.
Topics include:
Lesson 5:
- What happens to mass, volume and density when you heat and cool matter?
- How does matter of different phases expand and contract differently and how does this depends on density?
- How are these topics important to engineers when designing bridges, train tracks etc?
Lesson 6:
- What types of changes can take place when matter is heated?
- How can we classify these changes as physical or chemical changes?
Lesson 7
- What does the graph of temperature changes look like when matter changes phase from solid to liquid to gas?
- What is the vocabulary related to these changes: (melting, freezing condensation, evaporation, boiling)?
- How can you identify the boiling and melting points from the phase change graph?
