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. 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






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






3. 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






4. Atoms are made up of several tiny parts - At the center of an atom is a core called the __________ - which is made up of particles called protons and neutrons






5. 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






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

7. 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






8. Transferring of heat by the circulating motion of particles (in liquid or gas) - Occurs when hot air is less dense than cool air and therefore rises - When the heat moves in a circular pattern - convection currents are formed - Heat can be transferre






9. 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






10. Scratch hardness - indentation hardness - and rebound hardness






11. 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






12. In optics - refraction occurs when light waves travel from a medium with a given refractive index to a medium with another index Example: A ray of light will refract as it enters and leaves glass - assuming there is a change in the refractive index.






13. 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






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






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






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






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






18. 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






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






20. Take on the shape of their containers - yet cannot be compressed to any significant extent - The volume is constant unless evaporation is occurring






21. 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






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






23. The burning of coal also contributes to the formation of...






24. Obtained by two different means - fission and fusion






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






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






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






28. 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






29. State the specific plan on how to test the hypothesis - Create a written - step - by - step procedure - Determine the variables (any factor that can change in an experiment)






30. The particular state of water is determined by ___________ - the behavior of water at one atmosphere (sea level) - freezing at 0






31. 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






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






33. 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






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






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






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






37. 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






38. 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






39. 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?






40. Seems to travel in perfectly straight lines as rays - The direction of a ray changes at the interface between two transparent materials - like air and water






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






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






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






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






45. 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






46. 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






47. Multiply force but do not change the direction of the input force End: Fulcrum Middle: Output force Other end: Input force Examples: wheelbarrows - baby strollers - bottle openers






48. 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






49. Opposite process of nuclear fission - Yields energy when very light nuclei unite to a heavier nucleus - Stars (including the sun) derive their energy from nuclear fusion






50. 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
