The matter of the universe

  1. 1. THE MATTER OF THE UNIVERSE <ul>The wole known universe is formed by the same materials. <li>Matter: It is everything that has mass and volume.
  2. 2. Substance: It is each one of the different matter types.
  3. 3. Properties of matter:
  4. 4. General properties: They are those that all matter shares and allows us to recognize matter.
  5. 5. Mass: It is the quantity of matter that a body has.
  6. 6. Volume: It is the space that occupies this matter. </li></ul>
  7. 7. THE MATTER OF THE UNIVERSE <ul><li>Magnitude: It is any property of matter that you can measure, for example: the weight, the length, etc.
  8. 8. To measure: It is to compare a magnitude with the unit for example: 3 kg, 2 m., 50 km/h,etc.
  9. 9. International System of Units (S.I.): Almost all the countries of the world have adopted this system units. </li></ul>

  11. 11. THE MATTER OF THE UNIVERSE <ul><li>Density: It is the relationship between the mass of a body and the volume that it occupies.
  12. 12. d=m/v density= mass/volume
  13. 13. the most important unit to measure is the g/cm3, kg/m3.
  14. 14. Mass: It is the quantity of matter that a body has; the most important unit is the kg.
  15. 15. Weight: It is the force with which the Earth attracts a body.
  16. 16. Volume: It is the space that a body occupies, or how big or small that it is; the most important unit is the m3, cm3. </li></ul>
  17. 17. THE MATTER OF THE UNIVERSE <ul><li>The objects are manufactured with multiple materials. Each material is selected carefully for the function of its properties.
  18. 18. The growing industrialization demands that we look for new materials to manufacture novel objects or to improve old materials.
  19. 19. Our scientific knowledge also allows us to manufacture substances that have never existed. For example recently they have invented: medications, insecticides, plastics, varnishes, paintings, fibers, etc. </li></ul>
