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 liquid state is __________ between the solid and gaseous states with regard to molecular motion and attractive forces between molecules Examples: water - oil - milk - honey

6. 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






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






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






10. 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






11. 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






12. A source of electric light that works by incandescence - An electric current passes through a thin filament - heating it until it produces light - The enclosing glass bulb prevents the oxygen in the air from reaching the hot filament - which otherwis






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

14. 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






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






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






17. 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






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






19. 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






20. This is the variable that changes as a result of the manipulated variable. The dependent variable is observed and measured. Examples include determining how long various saltwater solutions take to freeze - and determining the number of cycles a pend






21. 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






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






23. 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






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






25. However - a fluorescent lamp converts electrical power into useful light more __________ than an incandescent lamp; lower energy costs offset the higher initial cost of the lamp






26. Obtained by two different means - fission and fusion






27. 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






28. Symbol: H Protons: 1 Neutrons: 0 Mass: 1






29. The mechanical advantage of a wedge is given by the ______________________ - Although a short wedge with a wide angle may do a job faster - it requires more force than a long wedge with a narrow angle






30. Height of the bounce of an object dropped o the material - related to elasticity






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






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






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