Questions and Answers

Why can't solids easily be compressed?

  • The particles are already packed very closely together. (correct)
  • The particles are held together by weak forces of attraction.
  • The particles are arranged in a random manner.
  • The particles have high energy levels.
  • According to particle theory, which state of matter has weak forces of attraction between particles?

  • Liquid (correct)
  • Gas
  • Solid
  • Plasma
  • Why do the particles in a solid vibrate to and fro?

  • Because the particles are not closely packed together
  • To move freely within the substance
  • Due to high energy levels (correct)
  • To maintain a definite shape

    Study Notes

    Particle Theory and States of Matter

    • Particle theory explains the properties of different states of matter (solids, liquids, gases) based on the arrangement and energy of particles.
    • The particles in a substance remain the same, but their arrangement and energy change between states of matter.

    Particles in a Gas

    • Particles in a gas are widely spaced and have a lot of energy, allowing them to move freely.
    • Example: Water can exist as a solid (ice), liquid, or gas (water vapor), with the same particles arranged differently in each state.

    Solids

    • Particles in solids are held very tightly together by strong forces of attraction.
    • Particles are in fixed positions in a regular arrangement, but vibrate slightly.
    • This arrangement explains the properties of solids, including:
      • Solids keep a definite shape and volume.
      • Solids can't flow like liquids.
      • Solids can't be easily compressed due to closely packed particles.
      • Solids are usually dense, with many particles in a small volume.

    Liquids

    • Particles in liquids are close together, but can move freely.
    • There are weak forces of attraction between particles in liquids.
    • Particles in liquids have more energy than in solids, but less than in gases.
