  3. What is 12?

  4. This force keeps the Moon in orbit around the Earth

  5. What is gravitational?

  6. This is the process represented by the following description: “sugar is added to water and a sweet liquid results after stirring”

  7. What is dissolving?

  8. The weight of a person on Earth is 6 times his weight on the Moon. The force responsible is…

  9. What is gravitational force?

  10. A large percentage of iron nails were kept in containers in a humid room,. Some of the containers were open and some were airtight. Sixty (60%) percent of the nails in open containers rusted. Which of the following information would be the MOST important to knowing if humidity caused the rust? a)% weakened by rust; b)precise number of nails in airtight containers c) % of nails in airtight container that rusted d)precise number of nails in open containers

  11. What is c; the percentage (%) of nails in airtight containers that rusted?

  12. Ice cubes melt into water Boiling point of water turns to steam Fireworks explode during a holiday Pieces of KCl dissolve in water This is the one that is the example of an exothermic chemical reaction…

  13. What is fireworks exploding during a holiday?

  14. We know Dimitri Mendeleev used atomic masses rather than atomic numbers to organize his periodic table—the reason is…

  15. What is scientist did not know about the atomic numbers in 1869?

  16. You are asked to determine in which of the following set ups an ice cube would melt the least: • Tightly wrapped in aluminum foil • In a tin can • In a glass jar • In a glass jar and the jar is completely covered in aluminum foil

  17. What is in a glass jar and the jar is completely covered in aluminum foil?

  18. Pauline needs to measure the sliding friction of brick, which method would be her best choice: • Attach the brick to a string and spring scale and read the scale • Drag the brick with a string attached to a spring scale so it gradually speeds up • Drag the brick by a string attached to the scale along a surface with a constant speed • Hang the brick from a string attached to the scale and read the force

  19. What is drag the brick by a string attached to the spring scale along the surface of a table at a constant speed and read the force?

  20. This property causes a lens to focus light

  21. What is reflection?

  22. This is the most UNSAFE way to heat a substance in a test tube: • Heating slowly • Adding the liquid to the test tube before turning on the flame • Using a low-energy flame • Looking down the test tube to check for boiling

  23. What is looking down the test tube to check for boiling?

  24. Soft drinks consist of a mixture of water, sugar, and flavoring, with carbon dioxide gas bubbled through it. The solvent is this…

  25. What is the water?

  26. This number should precede H2 in the chemical equation below in order for the equation to be balanced: ____ H2 + N2 2NH3

  27. What is 3?

  28. As you move left to right across a row of elements in the periodic table, this happens with the number of neutrons in a typical atom

  29. What is the number of neutrons increases?

  30. Of the following this one is the best choice to convert light energy into electrical energy • A windmill • A chemical storage battery • A solar cell • Rotating coils in a magnetic field

  31. What is using a solar cell?

  32. A helicopter is moving past some clouds at a velocity of 5km/hr North relative to the clouds. The clouds are moving past the ground at a velocity of 3.5 km/hr North. The helicopter is traveling this fast.

  33. What is 8.5 km/hr?

  34. In a restaurant kitchen, lamps are used to keep food warm. This type of electromagnetic radiation is emitted that is primarily responsible for keeping food warm

  35. What is infrared radiation?

  36. The International System of Unit (SI) is a standardized system of measurement used to express fundamental quantities in metric units. The metric unit for length, mass and time respectively is…

  37. What is meter, kilogram, and second?

  38. Carbon atoms can link themselves together into long chains and rings to form a vast number of highly complicated molecules. Which of the following BEST explains why: • They easily form ionic bonds with each other • They easily form covalent bonds with each other • They easily combine with atoms of oxygen • They easily become highly charged ions

  39. What is they easily form covalent bonds with each other?

  40. Of the following this one violates the law of conservation of energy: • A ball dropped from the top of a building increases in speed until it hits the ground • A block sliding freely on level ice increases speed until it hits a wall • A child playing on a swing moves fastest at the bottom of the swing’s path • The height a ball bounces decreases with each bounce

  41. What is a block sliding freely on level ice increases in speed until it hits a wall?

  42. Dale and Wallace are investigating static friction using a block and ramp. Their procedure is to raise the ramp in 5 degree increments while adding 5 gram masses to the block each time until it slides down the ramp. The statement that accurately describes this experimental procedure is… • This is a good experimental procedure • This is a flawed experimental procedure because they should be measuring the weight in newtons not grams • This is poor because they are changing too many variables • This is a flawed procedure because the masses may slide off the block.

  43. What is this is a poor experimental procedure because they are changing too many variables?

  44. A block of aluminum will be used to determine the density of aluminum. The block has the dimensions of 2 cm x 3 cm x 6 cm, this means the block has a volume of…
