35. Quiz Time

36. Properties of Matter Date

37. Physical Properties Get out your half sheet of paper with descriptions from yesterday. Share… Characteristics that can be observed or measured without changing the sample’s composition.

38. Examples: mass, volume, color, texture, shape, melting point, boiling point, density, solubility and magnetism.  Need any defined?  Density = mass / volume

39. Extensive vs. Intensive Extensive properties depend on the amount of substance.  Mass, volume, shape Intensive properties are independent of the amount of substance present.  Color, texture, melting point, boiling point, density, solubility, magnetism

40. States of Matter Draw the particles of a solid, liquid and gas. We use three ways to determine states of matter: the periodic table, common sense, and prior knowledge.

41. States of Matter cont. Solids – maintain their shape and volume (not compressible) Liquids – fluid in shape, but maintain volume (not compressible) Gas – fluid in shape, and do not maintain volume (compressible)

42. Practice Mercury (Hg) Zinc (Zn) Carbon (C) Salt (NaCl) Water (H 2 O) Air (N 2,O 2,CO 2 ) Alcohol (C 2 H 5 OH) Methane (CH 4 ) Neon (Ne) Chlorine (Cl 2 ) Bromine (Br 2 ) Snickers bar (CHOCoLaTe)

43. Chemical Properties Describe the ability of a substance to combine with or change into one or more other substances. Example: Has the ability to burn or rust.

44. Properties Vs. Changes Properties describe Changes actually occur

45. Physical change Alters the appearance of a substance, but does not change the composition. Examples: all phase changes, break, crush, split, crack  Melt/freeze  Vaporize/condense  Sublimation/deposition

46. Chemical Change AKA, chemical reactions, involve the changing of one or more substances into a new substance.  The new substance has new physical properties.
