Questions and Answers

What did James Clerk Maxwell investigate in the 1860s?

  • The trajectory of objects in classical mechanics
  • The laws of motion discovered by Newton
  • The behavior of gas particles in a closed container (correct)
  • The position and velocity of individual air molecules

    • How did Maxwell describe the movement of gas particles in the system he considered?

  • Like people in a crowded train station (correct)
  • Like planets orbiting the sun
  • Like cars on a highway
  • Like birds flying in formation

    • What is the main characteristic of gas particles, according to the text?

  • They all have different speeds
  • They collide with each other and the container walls (correct)
  • They move in a straight line
