Measurement/Density/Matter Test Review 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). 39. Be able to read a graduated cylinder. 40. Be able to calculate the interval spacing (directions below) on a variety of challenging graduated cylinders. 41. Be able to define a meniscus – the curvature of a liquid inside a graduated cylinder; always read from the bottom of the meniscus. 42. 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.
