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






2. 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






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






4. 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






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






6. 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






7. 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

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






9. Are inclined planes - Can convert a rotational force (torque) to a linear force - and vice versa - The ratio of threading determines the mechanical advantage of the machine - More threading increases the mechanical advantage






10. 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






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

12. 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






13. 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






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

15. 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






16. 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






17. Rates minerals and puts them on a scale from 1 to 10 (1 is the softest and 10 is the hardest) determined by the ability of a harder mineral to scratch a softer mineral - Talc is at 1 and diamond is at 10

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






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






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






21. A natural phenomenon by which objects with mass attract one another - Compels dispersed matter to coalesce - and thus it accounts for the very existence of the earth - the sun - and most of the macroscopic objects in the universe - Responsible for ke






22. 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






23. A rigid object that is used with an appropriate fulcrum or pivot point to multiply the mechanical force that can be applied to another object - Examples: wheelbarrow (the wheel works as the fulcrum) - scissors (the fulcrum is where the blades cross)






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






25. 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






26. 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






27. Displayed by permanent magnets and around electric currents






28. Hard matter is ______ with soft matter






29. When foreign substances are dissolved in water it creates a solution - Solutions with a pH of less than 7.0 are said to be acidic - and solutions with a pH greater than 7.0 are said to be basic or alkaline






30. Temperature scale -0






31. Obtained by two different means - fission and fusion






32. Symbol: U Protons: 92 Neutrons: 146 Mass: 238






33. 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






34. 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






35. Energy can be neither created nor destroy






36. 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






37. A flat surface whose endpoints are at different heights - resulting in a slope - By moving an object up an ___________ rather than completely vertically - the amount of force required is reduced - at the expense of increasing the distance the object
