Solid

Solid. Particles are tightly packed same shape same volume lowest amount of energy. Liquid. Particles are loosely packed changing shape same volume More energy than solids. Gas. Particles move freely changing shape changing volume (Fills container) More energy than liquids.

Presentation Transcript

  1. Solid • Particles are • tightly packed • same shape • same volume • lowest amount of energy

  2. Liquid • Particles are • loosely packed • changing shape • same volume • More energy than solids

  3. Gas • Particles move • freely • changing shape • changing volume (Fills container) • More energy than liquids

  4. Plasma • Made of freely moving • charged particles • HIGHEST energy, LOWEST density • Make-up 99% of the universe • Ex: Stars, Nebula, Neon Lights, Flames, Fluorescent light bulbs

  5. Matter and Energy

  6. Kinetic Theory of Matter (KTOM) • Theory that explains the motion of particles in states of matter

  7. KTOM—Point 1 • All matter is made of atoms and molecules that act like tiny particles

  8. KTOM—Point 2 • These tiny particles are in constant, random motion.

  9. KTOM—Point 3 • As the temperature of a substance is increased, the particles move faster.

  10. The Kinetic Theory of Matter is… a useful tool for visualizing the differences between the states of matter

  11. Energy and States of Matter • Energy: The ability to change or move matter • Changing states of matter = changes the amount of energy

  12. Evaporation: The change of a substance from a liquid to a gas

  13. Condensation: The change of a substance from a gas to a liquid

  14. Sublimation: The change of a substance from a solid to a gas

  15. Temperature vs. Heat Energy Plasma = very high temp and energy Energy is transferred in all changes of state Evaporates

  16. Law of Conservation of Energy • Energy cannot be created nor destroyed • Amount of energy does not change regardless of a Chemical Changeor Physical Change (Does not appear out of nowhere, but comes from another source) (Does not disappear, but changes form)
