Questions and Answers

What happens to gas molecules when they are compressed in an aerosol can?

  • They decrease in temperature and energy.
  • They form a solid structure.
  • They expand away from each other.
  • They squeeze together, creating a high-pressure zone. (correct)

    • Which statement best describes the Kinetic Molecular Theory of Gases?

  • Collisions between gas molecules are inelastic.
  • Gas molecules are attracted to each other.
  • Gas molecules move in random, constant, straight-line motion. (correct)
  • Gas molecules only move in curved paths.

    • What assumption is made about the volume of an ideal gas?

  • It expands infinitely.
  • It varies widely with pressure.
  • It occupies significant space.
  • It is considered to lack volume entirely. (correct)
