Transcript of "World of matter for class 9"

  1. 1. World of Matter
  2. 2. What is matter Matter is something that occupies space and has mass. Matter Non – Matter
  3. 3. Matter is made up of small particles Every substance is made up on small particles (called molecules). Each particle has the same properties as the original substance. A chemical bond holds the particles together. The strength of the bond between the particles determines many properties of that substance.
  4. 4. Particles of matter are in motion If you add a few drops of potassium permanganate to water you will observe that the color of the entire solution will change even if you don’t stir the solution. This is because particles of matter are always in motion. Particles of a solid vibrate in their place while those of liquid and gas can move about more freely.
  5. 5. There is gap between particles There is a lot of gap in between two particles of a substance. When you add potassium permanganate to water, the particles of potassium permanganate occupy the space between the water particles. Water molecule Potassium permanganate molecule Solid Liquid Gas There is very little empty space between particles in a solid. Gases have the maximum amount of empty space between particles
  6. 6. Properties of Matter Matter is made up on small particles. Particles of matter are held together by a chemical bond. Every particle of matter has the same properties. Particles of matter are in constant motion. There is gap between the particles of matter.
  7. 7. States of matter Plasma – Highly excited gas which has lost its electrons Solid Liquid Gas Plasma
  8. 8. States of matter Solid Has a fixed shape Has fixed volume Very hard to compress Little empty space between particles Particles vibrate in their place Strong chemical bonds hold the particles together Liquid No fixed shape Takes the shape of the container Has fixed volume Can be compressed a bit Little empty space between particles Particles can move about freely within the liquid Chemical bonds in liquids are weaker than in solids Gas No fixed shape No fixed volume Takes the volume of the container Easily compressible Large empty space between particles Particles have high energy and more about randomly Gases have the weakest chemical bonds amongst the three
  9. 9. Viscosity viscosity describes a liquid’s resistance to flow. Honey is more viscous then kerosene which is more viscous then water. Honey Kerosene Water

  11. 11. What happens on heating  Matter is made up on small particles which are in constant motion.  When you heat matter, the particles of matter absorb the heat energy and begin moving faster (in other words they gain kinetic energy).  As more energy is provided the chemical bond between the particles become weaker and hence there is change is the state of matter.  Latent heat is the heat absorbed or released when matter undergoes a change of state without a change in it temperature.  Latent heat of fusion – Melting  Latent heat of vaporization – Boiling

  13. 13. Conversion from on state to another LIQUID condensation evaporation sublimation deposition melting freezing De-ionization Ionization PLASMA GAS SOLID
  14. 14. Evaporation Evaporation is a type of vaporization of a liquid that occurs only on the surface of a liquid. Rate of evaporation depends up on surface area, temperature, flow of air and concentration of the substance in air (humidity) When the molecules collide, they transfer energy to each other. Sometimes during the transfer a molecule near the surface ends up with enough energy to escape. Evaporation is all about the energy in individual molecules.
  15. 15. Sublimation Some substances like ammonium chloride, camphor, dry ice (solid CO2) and naphthalene on heating transition directly from solid state to gaseous state. This direct transition from solid state to gaseous state is known as sublimation. Take some ammonium chloride in a china dish. Place an inverted glass funnel over it. Heat the dish gently. Ammonium chloride converts directly from solid state to gaseous state. Ammonium chloride vapours Cotton plug Inverted funnel Ammonium chloride solidified China dish Burnner
