  1. INTRODUCION to MATTER Ignacio Anguera de Sojo

  2. Whatismatter

  3. Whatismatter 1.- Properties of matter: • Whatis matter?

  4. Whatismatter 1.- matter: Matter is anything that has mass and takes up space

  5. Whatismatter 1.- matter: Matter is anything that has mass and takes up space Which two properties has all matter?

  6. Whatismatter 1.- matter: Matter is anything that has mass and takes up space Which two properties has all matter?

  7. Whatismatter 1.- matter: Matter is anything that has mass and takes up space Which two properties has all matter? My cat has mass and take up space, so it is MATTER!!!

  8. Whatismatter 2.- Volume: • Volume: amount of space occupied by an object (L, mL, m3, cm3). To measure: • Liquid: graduated cylinder (bottom meniscus) • Regular shape: V = length x width x height • Irregular shape: volume of water displaced

  9. Whatismatter 2.- Volume: • Volume: amount of space occupied by an object (L, mL, m3, cm3). To measure: • Liquid: graduated cylinder (bottom meniscus) • Regular shape: V = length x width x height • Irregular shape: volume of water displaced Which three ways we have to measure volume?

  10. Whatismatter 2.- Volume: • Volume: amount of space occupied by an object (L, mL, m3, cm3). To measure: • Liquid: graduated cylinder (bottom meniscus) • Regular shape: V = length x width x height • Irregular shape: volume of water displaced Which three ways we have to measure volume? Beaker

  11. Whatismatter 2.- Volume: • Volume: amount of space occupied by an object (L, mL, m3, cm3). To measure: • Liquid: graduated cylinder (bottom meniscus) • Regular shape: V = length x width x height • Irregular shape: volume of water displaced Which three ways we have to measure volume? The milk we drink at home comes in a regular shape container and it takes up a volume of one liter.

  12. Whatismatter 2.- Volume: • Meniscus: When we put a liquid on a graduated cylinder it forms a curve called MENISCUS

  13. Whatismatter 2.- Volume: • Volume of Irregular Shaped Solid Archimedes' principle indicates

  14. Whatismatter 2.- Volume: • Volume of Irregular Shaped Solid Archimedes' principle indicates The upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces

  15. Whatismatter 2.- Volume: • Volume of Irregular Shaped Solid

  16. Whatismatter 2.- Volume:

  17. Whatismatter 3.- Mass and Weight: Mass: amount of matter in an object. Always constant. Units: kg, g, mg. Weight: measure of the gravitational force in an object (N).

  18. Whatismatter 3.- Mass and Weight: Mass: amount of matter in an object. Always constant. Units: kg, g, mg. Weight: measure of the gravitational force in an object (N). Which are the differences between mass and weight?

  19. Whatismatter 3.- Mass and Weight: Mass: amount of matter in an object. Always constant. Units: kg, g, mg. Weight: measure of the gravitational force in an object (N). Which are the differences between mass and weight? It remains me to the images of Neil Armstrong walking in the moon in 1969. "That's one small step for a man, one giant leap for mankind".

  20. Whatismatter 3.- Mass and Weight: Mass: amount of matter in an object. Always constant. Units: kg, g, mg. Weight: measure of the gravitational force in an object (N). Which are the differences between mass and weight? It remains me to the images of Neil Armstrong walking in the moon in 1969.

  21. Whatismatter 4.- Inertia: Inertia: tendency of an object to resist being moved or, if it is moving, to resist a change in speed or direction until an outside force acts on the object.

  22. Whatismatter 4.- Inertia: Inertia: tendency of an object to resist being moved or, if it is moving, to resist a change in speed or direction until an outside force acts on the object. What has more inertia, a train or a bicycle?

  23. Whatismatter 4.- Inertia: Inertia: tendency of an object to resist being moved or, if it is moving, to resist a change in speed or direction until an outside force acts on the object. What has more inertia, a train or a bicycle? I hate to sweep under the sofa. Every time that I had to move it I have to overcome a lot of inertia!

  24. Physical Properties

  25. Whatismatter 5.- Physical Properties: Physical property: characteristic of a substance that can be observed or measured without changing the matter’s identity. Ex: thermal/electrical conductivity, state, density, solubility, ductility… Which of those is not a physical change?

  26. Whatismatter 5.- Physical Properties: Physical property: characteristic of a substance that can be observed or measured without changing the matter’s identity. Ex: thermal/electrical conductivity, state, density, solubility, ductility… Which characteristics have physical properties? Give 6 examples.

  27. Whatismatter 5.- Physical Properties: Density

  28. Whatismatter 5.- Physical Properties: Density Density: is the relationship between mass and volume (g/mL). DENSITY

  29. Whatismatter 5.- Physical Properties: Density Density: is the relationship between mass and volume (g/mL). Which of the following liquids has more density? And less density?

  30. Whatismatter 5.- Physical Properties: Density Density: is the relationship between mass and volume (g/mL). Which of the following liquids has more density? And less density? It remains me the oil spills responsible of environmental disasters.

  31. Whatismatter 6.- Physical Changes Physical Changes: Change of mater from one form to another without a change in chemical properties. Ex: production of sugar.

  32. Whatismatter 6.- Physical Changes Physical Changes: Change of mater from one form to another without a change in chemical properties. Ex: production of sugar. 1.- Sugar cane grow in fields and contain the sugar dissolved in liquid inside the plant

  33. Whatismatter 6.- Physical Changes Physical Changes: Change of mater from one form to another without a change in chemical properties. Ex: production of sugar. 2.- The sugar and shredded. Then, they cane is cut. The cane pieces are washed are squeezed to press out the juice containing the sugar cane.

  34. Whatismatter 6.- Physical Changes Physical Changes: Change of mater from one form to another without a change in chemical properties. Ex: production of sugar. 3.- The water is evaporated form the juice and raw crystals form

  35. Whatismatter 6.- Physical Changes Physical Changes: Change of mater from one form to another without a change in chemical properties. Ex: production of sugar. The sugar molecules in the crystals are the same sugar molecules that were stored in the sugar cane plants.

  36. Chemical Properties

  37. PhysicalandChemicalchanges 7.- Chemical Properties

  38. Whatismatter 5.- Chemical Properties Chemical property: describe a substance’s ability to participate in chemical reactions (reactivity, flammability).

  39. Whatismatter 5.- Chemical Properties Chemical property: describe a substance’s ability to participate in chemical reactions (reactivity, flammability). Which characteristics have all chemical reactions?

  40. Whatismatter 5.- Chemical Properties Chemical property: describe a substance’s ability to participate in chemical reactions (reactivity, flammability). Which characteristics have all chemical reactions? If you cut an apple, the flesh of apples turn brown due to oxidation.

  41. Whatismatter 5.- Chemical Properties Chemical changes: the composition of an object changes. Which characteristics have all chemical reactions? If you cut an apple, the flesh of apples turn brown due to oxidation.
