CSET Physical Science 3

Subjects : cset, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Solar - Chemical - Electrical - Magnetic - Nuclear - Sound - Light - Electromagnetic - Mechanical (motion)






2. Made by combining two or more different materials without a chemical reaction occurring (the objects do not bond together) - They are the product of a mechanical blending or mixing of chemical substances - Either homogeneous or heterogeneous






3. Temperature scale -0






4. Results when electrical charges buildup or increase on the surface of a material - here - there is no current flowing as would be found in electrical outlets - When certain materials are rubbed together - electrons can move from one object to the oth






5. State the specific plan on how to test the hypothesis - Create a written - step - by - step procedure - Determine the variables (any factor that can change in an experiment)






6. As of 2006 - the table contains _____ chemical elements whose discoveries have been confirmed - 94 are naturally found on the earth - and the rest are synthetic elements that have been produced artificially in particle accelerators






7. Releases energy when a heavy nucleus splits into smaller fragments - Used in power plants and atomic bombs






8. Symbol: C Protons: 6 Neutrons: 6 Mass: 12






9. This is the one factor that will be intentionally changed during the experiment. Examples include changing the amount of salt that is added to water to determine its freezing point; introducing different soil types in germinating seeds; and changing






10. The terms gravitation and gravity are mostly interchangeable in everyday use - refers specifically to the gravitational force exerted by the earth on objects in its vicinity






11. Solids - liquids - and gases






12. The number of protons of that element - No two elements have the same atomic number - Elements in the periodic table are arranged in order of increasing atomic number






13. These are the factors that are kept exactly the same in an experiment. In an experiment on plant growth - the variables could include amount of sunlight - type of soil - amount of water - and type of plant. Only one factor at a time is changed - whil






14. The top of a wave's 'hill'






15. For every action (applied force) - there is an equal and opposite reaction

16. Move around the nucleus in electron clouds - have a negative charge - and they are attracted to the positively charged protons in the nucleus - This attraction keeps the electrons in orbit around the nucleus






17. Also generates a magnetic field - demonstrating an intimate connection between electricity and magnetism






18. Elements are assigned atomic numbers equal to the __________ in the nucleus of their atoms - Each element has a different number of protons






19. A compound and portable inclined plane - A triangular - shaped tool used to separate two objects or portions of an object - lift an object - or hold an object in place - It functions by converting a force applied to its blunt end into forces perpendi






20. Some gases can transition directly to a solid Example: the formation of frost






21. As temperature increases (at a fixed pressure) - so does volume Examples: air - helium - steam

22. The resulting piece of paper or solution with water becomes a ________ (one of the oldest) - used to test materials for acidity






23. If the pressure increases - the volume decreases; the reverse is true as well

24. The liquid state is __________ between the solid and gaseous states with regard to molecular motion and attractive forces between molecules Examples: water - oil - milk - honey






25. The burning of coal also contributes to the formation of...






26. Take on the shape of their containers - yet cannot be compressed to any significant extent - The volume is constant unless evaporation is occurring






27. Can multiply force or distance depending on the location of the fulcrum End: Output force Middle: Fulcrum Other end: Input force Examples: seesaws - scissors - pliers






28. Elements with similar properties fall into the same vertical columns on the preriodic table to form _____ - Properties of elements change greatly across any one row (period)






29. Account for 17 elements in the periodic table - Lack the properties of metals but are very common - Include oxygen - nitrogen - and carbon - 7 metalloid elements - and 7 gases - Poor conductors of electricity






30. Explains why objects appear bent as light passes from one transparent object into another - Light travels at different speeds through different objects (faster through air than through water or glass) - Responsible for rainbows and for the splitting






31. Transition of heat through a medium - From a region of higher temperature to a region of lower temperature - Heat energy is transferred from one material to another by direct contact - Metals are good conductors of heat






32. Some of the light is reflected - the angle of reflection being equal to the...






33. A mechanical device that changes the direction or magnitude of a force - The simplest mechanisms that use mechanical advantage to multiply force - Uses a single applied force to do work against a single load force






34. The ability to perform work - _______ transformations result when a change of form takes place - All forms of ________ can be converted into other forms






35. Kinetic energy: energy possessed by a moving object - An object in an unstable position has potential energy - for the position could be converted into movement Example: a baseball thrown vertically upward






36. A compressed gas pushes out __________ in all directions






37. This is the variable that changes as a result of the manipulated variable. The dependent variable is observed and measured. Examples include determining how long various saltwater solutions take to freeze - and determining the number of cycles a pend






38. Symbol: He Protons: 2 Neutrons: 2 Mass: 4






39. Involve one substance changing states (not one substance changing into another) - Typically reversible Example: water - Can change from a gas (water vapor) to a liquid (water) to a solid (ice) - but the water molecules do not change






40. Temperature scale named after the German physicist Daniel Gabriel Fahrenheit (1686-1736) - who proposed it in 1724 - On this scale - the freezing point of water is 32






41. A first - class lever - In its simplest form it consists of a rod attached to a wheel so that their movements are coupled when one of the parts is turned






42. Arranges all of the known elements from left to right and top to bottom in order of increasing atomic number - and they generally coincide with their increasing atomic mass






43. The path or circuit an electric current flows - Electricity requires a complete path for the electrons to flow - If the path is broken and there are not alternative paths for the electrons to follow - the electrons will not move - make it possible fo






44. The portion of the light that crosses the boundary is - however - deflected in another direction - and the ______ does not equal the angle of incidence






45. Glass has a higher ___________ than air and the different frequencies of light have different wavelengths (dispersion) - causing them to be refracted at different angles - so that you can see them - The different frequencies correspond to different c






46. Salt has a ___________ than water and therefore doesn't evaporate with the water






47. Characterized by their ability to retain their shape - Relatively incompressible - Melt when heated and vaporize only slightly - All substances become solid if cooled sufficiently Examples: rocks - crystals - wood - feather - ice
