Solid: 1. Definite shape and volume, 2. Particles tightly packed, 3. Minimal compressibility, 4. Low energy, 5. Strong intermolecular forces. Liquid: 6. Takes shape of container, 7. Fixed volume, 8. Moderate energy, 9. Weaker intermolecular forces than solids. Gas: 10. No definite shape or volume, 11. Highly compressible, 12. High energy, 13. Particles widely spaced, 14. Weakest intermolecular forces.

FAQs & Answers

  1. What is the main difference between a solid and a liquid? A solid has a definite shape and volume with tightly packed particles, while a liquid has a fixed volume but takes the shape of its container with particles that are less tightly packed.
  2. Why are gases highly compressible compared to solids and liquids? Gases have particles that are widely spaced and have weak intermolecular forces, allowing them to be compressed easily unlike solids and liquids where particles are closely packed.
  3. How does particle energy differ among solids, liquids, and gases? Particles in solids have low energy and vibrate in place, liquids have moderate energy allowing flow, and gases have high energy with particles moving freely at high speeds.
  4. What role do intermolecular forces play in states of matter? Intermolecular forces determine how tightly particles stick together; strongest in solids, weaker in liquids, and weakest in gases, affecting shape, volume, and compressibility.
