# Measurement/Density/Matter Test Review

```Measurement/Density/Matter Test Review
February 17, 2015
Items new to this test:
1. What is the basic unit of measurement for weight and mass in the metric system? gram
2. What are the units of measurement that we have been using for volume? Milliliter and cubic
centimeters. (ml and cm3)
3. What are the units of measurement that we have been using for length?? Millimeter and centimeter
(mm and cm)
4. Define volume – the space an object takes up.
5. Define mass – the amount of particles an object contains.
6. Define weight – the force of gravity acting on an object.
7. Define length – distance from one point to another.
8. What is the formula for finding the volume of a regular solid? (length x width x height).
9. Be able to read a triple beam balance like the following:
10. Know how to read a metric ruler correctly.
12. Be able to calculate the interval spacing on a variety of challenging graduated cylinders.
13. Be able to define a meniscus – the curvature of a liquid inside a graduated cylinder; always read from
the bottom of the meniscus.
14. Know how to measure the volume of an irregular object such as a marble or a rock using either water
displacement or an overflow canister.
15. Be able to calculate the density of different materials and compare (density = mass/volume).
16. Be able to analyze a problem and decide which material will float or sink based on density calculations
(the higher density will always sink).
Items from the previous test that might be good to know for this test:
17. Define matter
18. Define temperature – the vibration of particles or molecules; temperature can stop changing.
19. Define heat – the vibration of particles or molecules; heat never stops changing.
20. Identify the three phases of matter
o Define solid, and give examples
o Define liquid, and give examples
o Define gas, and give examples
21. Describe the arrangement of molecules in a solid, liquid, and gas
22. Describe how the molecules move in a solid, liquid, and gas
23. Define evaporation (as a phase change) and give an example
24. Define condensation (as a phase change) and give an example
25. Define melting (as a phase change) and give an example
26. Define freezing (as a phase change) and give an example
27. Describe the direction of heat in a phase change
28. Define exothermic
29. Define endothermic
30. Explain what happens to a material’s temperature during a phase change
31. Be able to compare and contrast temperature and heat
32. Be able to compare and contrast different phase changes
33. 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).
Some things to consider:
1.
2.
3.
4.
5.
Remember to review science sponges
Review homework
Review general notes
Review labs and lab results
Reviewing studystack only is at best going to earn you a passing grade (C)
