Solid: Has a fixed shape and volume. Liquid: Takes the shape of its container but has a fixed volume. Gas: Fills the entire volume of its container. Solid Particles: Tightly packed, vibrating in place. Liquid Particles: Less tightly packed, sliding past each other. Gas Particles: Widely spaced, moving freely. Solid: Incompressible. Liquid: Slightly compressible. Gas: Highly compressible. Solid: High density. Liquid: Lower density than solids but higher than gases. Gas: Low density.

FAQs & Answers

  1. What distinguishes a solid from a liquid? A solid has a fixed shape and volume with tightly packed particles vibrating in place, while a liquid takes the shape of its container but maintains a fixed volume with particles sliding past each other.
  2. Why can gases fill any container? Gases have widely spaced particles that move freely, allowing them to expand and fill the entire volume of their container.
  3. How does compressibility differ among solids, liquids, and gases? Solids are incompressible due to tightly packed particles, liquids are slightly compressible, and gases are highly compressible because of the large spaces between particles.
  4. What causes the difference in density between solids, liquids, and gases? Density differences arise from particle arrangement: solids have high density due to tight packing, liquids have lower density because particles are a bit more spread out, and gases have low density due to widely spaced particles.
