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. 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






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






3. 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






4. 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






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

7. Scratch hardness - indentation hardness - and rebound hardness






8. Known as insulators - In materials that act as insulators - the electrons are held tightly inside their atoms and the electrons cannot move freely - Include plastic - rubber - glass - air - and wood






9. The ratio of the output to the input force - Also called leverage - Results in less force applied over a greater distance - Helps to make work easier






10. In physics and engineering - it means the strength of the gravitational pull on the object (how heavy it is - measured in newtons)






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






12. 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






13. Hard matter is ______ with soft matter






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






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






16. 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

17. Collect Data (results) - Analyze the data to look for patterns or trends - Record measurements and observations during the experiment - Present data in a graph - table - or another form






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






19. A form of energy that can be used to produce sound - light - heat - and power - it exists where the number of negative electrons does not precisely equal the number of positive protons - Electrons are held in the atom by an electrical force and have






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






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






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






24. 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






25. 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






26. Mechanical advantage of an inclined plane is the ______________ it spans - The inclined plane allows the same work to be done with a smaller force exerted over a greater distance Example: ramp






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






28. 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






29. 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)






30. A conclusion is a summary and an explanation of the results of an experiment - Does the data support the hypothesis? If not - a new hypothesis can be formed






31. 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






32. Relies on the the first law - The acceleration of an object is proportional to the force applied (the more force - the more acceleration)

33. 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






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






35. 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






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






37. The rate of change of velocity with time a = ?v/?t (acceleration = change of velocity/change of time)
