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. Top: Output force (resistance) Middle: Input force (effort) End: Fulcrum Examples: baseball bat - fishing pole - shovel






2. Anything that has mass and occupies space - Everything you see and touch is composed of matter






3. When the electrons flow in one direction - the flowing electricity is referred to as current - An electric current is simply a flow of electrons through a wire






4. 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






5. Heat can be converted to motion - and motion can produce heat






6. Transferring of heat by the circulating motion of particles (in liquid or gas) - Occurs when hot air is less dense than cool air and therefore rises - When the heat moves in a circular pattern - convection currents are formed - Heat can be transferre






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






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

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






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






12. A compound composed of one atom of sodium and one atom of chlorine (NaCl - sodium chloride)






13. Solar - Chemical - Electrical - Magnetic - Nuclear - Sound - Light - Electromagnetic - Mechanical (motion)






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






15. The pitch of a sound depends on how fast the particles of a medium vibrate






16. Energy can be neither created nor destroy






17. 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






18. Energy generated from natural sources (such as sunlight - wind - rain - tides - and geothermal heat) which are renewable (naturally replenished)






19. Symbol: O Protons: 8 Neutrons: 8 Mass: 16






20. A wave's height - the distance between its resting position and its crest






21. A change of one substance into a different substance - Occurs whenever compounds are formed or decomposed - During this reaction - there is a rearrangement of atoms that makes or breaks chemical bonds - This change is usually not reversible - unlike






22. A hypothesis is an attempt to answer the question or predict the outcome - - A hypothesis is a possible explanation for a set of observations






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






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

25. 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






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. In each element's square - the ________ is in the middle - the atomic weight is usually directly below the symbol - the atomic number is usually shown at the top of the square






28. Made up of molecules with the composition H20 - One _____ molecule is built from two atoms of hydrogen and one atom of oxygen






29. Multiply force but do not change the direction of the input force End: Fulcrum Middle: Output force Other end: Input force Examples: wheelbarrows - baby strollers - bottle openers






30. Obtained by two different means - fission and fusion






31. List the specific materials to be used in the experiment - This allows for replication of the experiment






32. Designed to separate substances in a liquid through vaporization - Usually carried out in an apparatus called a still - which requires a boiler - a condenser - and a receiver Example: Purify ocean water






33. 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






34. Displayed by permanent magnets and around electric currents






35. The law of inertia - Without outside forces (such as gravity or friction) - an object at rest will remain at rest - while an object in motion will never stop or deviate from its course

36. Formed by the chemical combination of two or more elements in a fixed ratio Example: water






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






38. A compressed gas pushes out __________ in all directions






39. 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






40. For smooth surfaces - the angle at which light is incident on the surface equals the angle at which it is reflected






41. 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






42. Expand to fill any available space - a compressible fluid - with its volume determined by the pressure and temperature of the environment






43. 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






44. A water - soluble mixture of different dyes extracted from lichens - It is often absorbed onto filter paper






45. 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






46. Hard matter is ______ with soft matter






47. A temperature interval of one degree F is an interval of 5/9 of a degree C - The Fahrenheit and Celsius scales coincide at -40






48. Show the number of molecules or formula units of the reactants and products - Example: nitrous oxide is a colorless - odorless gas that causes mild hysteria when inhaled - hence the name laughing gas; it is prepared by heating ammonium nitrate crysta
