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. 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

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






4. The distance between two consecutive points on a wave (crest to crest)






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






6. Transferring of heat by emission and dissemination of waves or particles - Generated when heat from the movement of charged particles within atoms is converted to electromagnetic radiation - Electromagnetic radiation emitted from the surface of an ob






7. 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






8. 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






9. A grooved wheel with a rope or other item wrapped around it - used to change the direction of an applied force - change the amount of force - transmit rotational motion - or realize a mechanical advantage in either a linear or a rotational system of






10. Other indicators of the ________ of an acid are that when acids react with metals - hydrogen gas is released causing bases to feel soapy when touched






11. 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






12. 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






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






14. Resistance to fracture or plastic (permanent) deformation due to friction from a sharp object






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






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






17. 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






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






19. Makes it possible for some elements and compounds to transition from a solid to gas phase without becoming a liquid Example: a block of dry ice (CO2) - which will turn into a gas at room temperature






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






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






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






23. A difference between two temperatures or an uncertainty






24. 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






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






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






27. The earth's __________ orients the iron needles of navigational compasses






28. 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






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






30. 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






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






32. 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






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

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






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






37. 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






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






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