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 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






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






3. A gas - discharge lamp that uses electricity to excite mercury vapor - The excited mercury atoms produce short - wave ultraviolet light that then causes a phosphor to fluoresce - producing visible light






4. 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






5. The portion of the light that crosses the boundary is - however - deflected in another direction - and the ______ does not equal the angle of incidence






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. 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






8. The sum of the protons and neutrons gives an ______________ for the element






9. Energy can be neither created nor destroy






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






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






12. Displayed by permanent magnets and around electric currents






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






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






15. 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






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






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






18. 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






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






20. 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






21. 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






22. 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






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






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. Show the number of molecules or formula units of the reactants and products - Example: nitrous oxide is a colorless - odorless gas that causes mild hysteria when inhaled - hence the name laughing gas; it is prepared by heating ammonium nitrate crysta






26. 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






27. In everyday situations - the weight of an object is ____________ - which usually makes it acceptable to use the same word for both concepts






28. 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)






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






30. 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






31. List the specific materials to be used in the experiment - This allows for replication of the experiment






32. Major greenhouse gases






33. The beginning of scientific wisdom - The physicist's first reaction to a new idea is to ask: Can it be measured? Can I describe it with numbers?






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






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


36. A measure of the acidity or basicity of a solution - The ____ scale is not an absolute scale; it is relative to a set of standard solutions whose pH is established by international agreement - these measurements are important for medicine - biology -






37. 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
