Tuesday, December 20, 2011
1. Define matter
2. Be able to give examples of both non-matter and matter
3. Be able to identify an experiment that can determine if something is matter or non-matter
4. Define temperature – the vibration of particles or molecules; temperature can stop changing.
5. Define heat – the vibration of particles or molecules; heat never stops changing.
6. Identify the three phases of matter
7. Define solid, and give examples
8. Define liquid, and give examples
9. Define gas, and give examples
10. Describe the arrangement of molecules in a solid, liquid, and gas
11. Describe how the molecules move in a solid, liquid, and gas
12. Define evaporation (as a phase change) and give an example
13. Define condensation (as a phase change) and give an example
14. Define melting (as a phase change) and give an example
15. Define freezing (as a phase change) and give an example
16. Describe the direction of heat in a phase change
17. Define exothermic
18. Define endothermic
19. Explain what happens to a material’s temperature during a phase change
20. Be able to compare and contrast temperature and heat
21. Be able to compare and contrast different phase changes
22. Look at a plot of temperature changing and describe the states of matter and where the phase
changes occur (A walk up and down the phase change graph homework).
23. Define the law of conservation of matter
24. Compare a closed system to an open system
Items from the previous test that might be good to know for this test:
25. What is the basic unit of measurement for weight and mass in the metric system? gram
26. What are the units of measurement that we have been using for volume? Milliliter and cubic
centimeters. (ml and cm3)
27. What are the units of measurement that we have been using for length?? Millimeter and
centimeter (mm and cm)
28. Define volume – the space an object takes up.
29. Define mass – the amount of particles an object contains.
30. Define weight – the force of gravity acting on an object.
31. Define length – distance from one point to another.
32. What is the formula for finding the volume of a regular solid? (length x width x height).
33. Be able to measure a line like the following in centimeters and convert to millimeters:
_________________________________________
34. Be able to read a triple beam balance like the following:
35. Know how to read a metric ruler and meter stick correctly.
36. Know how to convert between millimeters and centimeters. Know how to show your work!
37. Be able to calculate the density of different materials and compare (density = mass/volume).
38. Be able to analyze a problem and decide which material will float or sink based on density
calculations (the higher density will always sink).
