Physical and Chemical Properties

Physical Properties • Physical property- A characteristic that can be observed using one of the five senses • Physical Change- any change that can be reversed. • Common Physical properties. Color, state of matter, mass, weight, volume, size,

Physical Properties • Solubility- Amount of a substance that will dissolve in 100 grams of water • Melting point- The point at which a solid changes to a liquid • Boiling point- The point at which a liquid changes to a gas • Density- the amount of matter in a given object –D=M/V

Physical Properties Substance Color Bromine State Density Melting Point Boiling Point Red-Brown Liquid 3. 12 -7 59 Chlorine Yellowish Gas . 0032 -101 -34 Sulfur Yellow Solid 2. 07 115 445 Water Colorless Liquid 1 0 100

Size Dependent Property • Size dependent property- a property that changes due to size ex. Mass, weight, length, volume

Size Independent Properties • Size independent properties- A property that does not change according to size ex. Density (mass/volume), Melting point, Boiling point.

Behavior • Behavior- the way a specific substance reacts – Example-Lodestone is magnetic

Chemical Properties • Chemical property- The ability of a substance to undergo change that alters its identity. • Chemical reaction- The change that alters a substances identity. ex. Burning, rusting

Chemical Changes • 1. 2. 3. Ways to Identify a chemical reaction Gas given off Change of color Change of temperature (chemical reactions usually create heat even if it is a very small amount)
