Properties of Matter Date:

Physical Properties Characteristics that can be observed or measured without changing the sample’s composition.  Composition: the chemical make up of a compound

Examples of physical properties State of Matter Color Texture Shape Solubility Magnetism Mass Volume Density Melting point Boiling point

States of Matter The basic states of matter are: Solid, Liquid, Gas Move your chairs RESPECTFULLY to be a solid Liquid Gas

State of matter can be determined from  The periodic table  Common sense  Prior knowledge

States of Matter cont. State of Matter Fluid or Rigid CompressibilityShapeVolume

Chemical Properties Describe the ability of a substance to combine with or change into one or more other substances.

Examples The ability to: Burn Rust/Oxidize

Properties Vs. Changes Properties describe Changes actually occur

Physical change Alters the appearance of a substance, but does not change the composition. What was composition again?

Examples of physical changes All phase changes  Melt/freeze  Vaporize/condense  Sublimation/deposition Break Crush Split Crack

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

Law of Conservation of Mass Mass is neither created nor destroyed during any change – it is conserved.
