Questions and Answers

Which of the following best explains why a kilogram of feathers and a kilogram of sugar do not have to be equal in amount or sample size?

  • The mass is the same for both despite taking up different volumes. (correct)
  • The atomic structure of feathers differs from that of sugar.
  • The density of feathers is higher than that of sugar.
  • The weight of feathers is greater than that of sugar.

    • Why is corrosion considered a chemical property rather than a physical property?

  • It only affects the surface atoms of the metal.
  • It results in the metal becoming magnetic.
  • It occurs when oxygen reacts with the metal, leading to a change at the molecular level. (correct)
  • It changes the color and texture of the metal.

    • What is a common example of corrosion mentioned in the text?

  • Rusting steel (correct)
  • Polishing metal
  • Painting a metal surface
  • Heating a metal rod
