Lecture 2.1- Properties of Matter

  1. 1. Lecture 2.1- Properties of MatterA property is a quality or attribute. Is the property Intensive or Extensive? Is the property Physical or Chemical?
  2. 2. Describing MatterProperties used to describe matter can be classified as extensive or intensive.
  3. 3. Describing MatterProperties used to describe matter can be classified as extensive or intensive.– An extensive property depends on the amount of matter in a sample.
  4. 4. Describing MatterProperties used to describe matter can be classified as extensive or intensive.– An extensive property depends on the amount of matter in a sample.– An intensive property depends on the type of matter in a sample, not the amount of matter.
  5. 5. 2.1 Describing Matter– Extensive properties depend on amount.
  6. 6. 2.1 Describing Matter– Extensive properties depend on amount. • The mass of an object is a measure of the amount of matter the object contains.
  7. 7. 2.1 Describing Matter– Extensive properties depend on amount. • The mass of an object is a measure of the amount of matter the object contains. • The volume of an object is a measure of the space occupied by the object.
  8. 8. 2.1 Describing Matter– Extensive properties depend on amount. • The mass of an object is a measure of the amount of matter the object contains. • The volume of an object is a measure of the space occupied by the object.
  9. 9. 2.1 Describing Matter– Extensive properties depend on amount. • The mass of an object is a measure of the amount of matter the object contains. • The volume of an object is a measure of the space occupied by the object. The big ball has more mass and volume than the little ball.
  10. 10. 2.1 Describing MatterIntensive Properties The hardness of a bowling ball is an example of an intensive property.
  11. 11. Is flammability an extensive or intensiveproperty?
  12. 12. 2.1 Identifying SubstancesMatter that has a uniform and definite composition is called a substance. A substance is pure.
  13. 13. 2.1 Identifying SubstancesEvery sample of a given substance hasidentical intensive properties.
  14. 14. 2.1 Identifying Substances Every sample of a given substance has identical intensive properties.Example- Every sample of pure water is a clear, odorless, liquid at room temperature. It will boil at 100ºC and freeze at 0ºC.
  15. 15. 2.1 Identifying Substances Every sample of a given substance has identical intensive properties.Example- Every sample of pure water is a clear, odorless, liquid at room temperature. It will boil at 100ºC and freeze at 0ºC.These properties are intensive because they do not depend on how big the sample is.
  16. 16. 2.1 Identifying Substances• A physical property can be observed or measured without changing the substance’s composition.• Hardness, color, and crystal shape are examples of physical properties.
  17. 17. 2.1 Identifying Substances
  18. 18. 2.1 States of Matter Three states of matter are solid, liquid, and gas.
  19. 19. 2.1 States of MatterA solid is a form of matter that has a definite shape and volume.
  20. 20. 2.1 States of MatterA liquid is a form of matter that has an indefinite shape (it flows) but a definite volume.
  21. 21. 2.1 States of MatterA gas is a form of matter that takes both the shape and volume of its container.
  22. 22. 2.1 States of MatterA gas is a form of matter that takes both the shape and volume of its container.The gas state is the only state of matter that is compressible.
  23. 23. 2.1 States of MatterVapor describes agas that is usually aliquid or solid atroom temperature,as in water vapor.
  24. 24. States of matter- the 3 forms in which matter exists
  25. 25. States of matter- the 3 forms in which matter existsSolid- particles are tightlypacked in a rigid structure.Has a fixed shape and volume!
  26. 26. States of matter- the 3 forms in which matter existsSolid- particles are tightlypacked in a rigid structure.Has a fixed shape and volume!
  27. 27. States of matter- the 3 forms in which matter existsSolid- particles are tightlypacked in a rigid structure.Has a fixed shape and volume!Liquid- particles are very closebut can move around eachother. Takes the shape of itscontainer, but has a fixed volume.
  28. 28. States of matter- the 3 forms in which matter existsSolid- particles are tightlypacked in a rigid structure.Has a fixed shape and volume!Liquid- particles are very closebut can move around eachother. Takes the shape of itscontainer, but has a fixed volume.
  29. 29. States of matter- the 3 forms in which matter existsSolid- particles are tightlypacked in a rigid structure.Has a fixed shape and volume!Liquid- particles are very closebut can move around eachother. Takes the shape of itscontainer, but has a fixed volume.Gas- particles are far apart andmoving fast. Has no fixed shape orvolume.
  30. 30. States of matter- the 3 forms in which matter existsSolid- particles are tightlypacked in a rigid structure.Has a fixed shape and volume!Liquid- particles are very closebut can move around eachother. Takes the shape of itscontainer, but has a fixed volume.Gas- particles are far apart andmoving fast. Has no fixed shape orvolume.
  31. 31. Substances go from solid to liquid to gasas energy increases.
  32. 32. 2.1 Physical ChangesDuring a physical change,some properties of amaterial change, but thecomposition of the materialdoes not change.As gallium melts in a person’shand, the shape of the samplechanges, but the composition ofthe material does not change.
