Document Summary

Physical properties: attributes which distinguish one substance from another (think of the 5 senses) Examples: malleablility, ductility (ability to pull into wire, characteristic of metals), conductive, thermal conductivity (specific heat properties), taste, appearance, changing of state of matter. Chemical properties: behavior a substance displays when its composition is subject to change. Examples: iron reacts with oxygen to form rust, calcium carbonate neutralizes stomach acid. Caco3 (s) + 2h (aq)+ 2h2o (l) + co2 (g) + ca2+ (aq) Solids displays fluid motion (fixed shape), will not conform to the shape of its container, comprised of molecules tightly packed, most condensed material. Liquids will conform to the shape of its container, container is filled only to the extent of liquid"s own volume. Gases will conform to the shape of container, will fill the entire container, gaseous state contains the highest molecular randomness.
