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. Solids - liquids - and gases






2. Energy taken from finite resources that will eventually dwindle - becoming too expensive or too environmentally damaging to retrieve - Fossil fuels include coal - petroleum - and natural gas - Fossil fuels are limited and nonrenewable and contribute






3. Electricity flows easily through materials that conduct electricity - Include metals such as aluminum (Al) - iron (Fe) - nickel (Ni) - silver (Ag) - and gold (Au)






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






7. 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






8. A degree on the Fahrenheit scale is 1/180th of the interval between the __________ and boiling point






9. Occurs when light travels only in straight lines - An object is visible because light is reflected from the object into our eyes






10. Unlike incandescent lamps - fluorescent lamps always require a ______ to regulate the flow of power through the lamp






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






12. 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






13. A difference between two temperatures or an uncertainty






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

15. The north pole of one magnet attracts the ___________ of another - but like poles repel each other - Either pole can attract unmagnetized iron objects






16. For a homogeneous object - density is determined by dividing the mass by the volume (D = M/V) The mass is normally measured with an appropriate scale or balance - The volume may be measured directly (from the geometry of the object) or by the displac






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






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






19. A compressed gas pushes out __________ in all directions






20. After a rainstorm - the air is full of tiny drops of water - Each drop acts as a prism - splitting the light into the colors of the spectrum






21. Resistance to plastic (permanent) deformation due to a constant load from a sharp object






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

23. The rate of change of position with time v = ?d/?t (velocity = change of distance/change of time)






24. Refers to various properties of matter in the solid phase that give it a high resistance to its shape changing when force is applied






25. The amount of matter in a chemical substance - In everyday usage - is commonly confused with weight






26. Protons have a __________ electrical charge - and neutrons have no charge






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






28. 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






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






30. The characteristics that makes up the physical composition of a substance - Include color - form - electrical conductivity - and density






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






32. Example of chemical change - Iron chemically reacts with air and water to form rust (ferrous oxide) and is unable to change back to iron






33. Heat tends to move from a high - temperature region to a low- temperature region - This heat transfer may occur by the mechanisms of conduction - radiation - and convection






34. The branches of natural sciences that study the nature and properties of energy and non - living matter






35. 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






36. Symbol: Fe Protons: 26 Neutrons: 30 Mass 56






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






38. 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






39. 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






40. 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






41. Composed of only one atom and cannot be separated into different substances except in some instances by radioactive decay or by nuclear reactions






42. Form a question (state the problem) - A scientific question is one that can be answered on the basis of evidence and that can be measured - The question often asks - 'What effect will something have
