Physical and Chemical Properties

Physical Properties Characteristics that distinguishes one type of matter from another and can be observed as long as the identity of the matter being observed is not changed.

Physical Properties Density Melting Point Boiling Point

Density The amount of matter in a given space, or volume D=M/V Corn Oil Water Shampoo Dish Detergent Antifreeze Maple Syrup The amount of matter in a given space, or volume D=M/V Example: Oil & Water ________

Changes in States of Matter Change between solid and liquid Melting: Solid → Liquid Freezing: Liquid → Solid Change between liquid and gas Vaporization: Liquid → Gas Evaporation = only on surface of liquid Boiling = inside and on surface of liquid Condensation: Gas → Liquid Change between solid and gas Sublimation: Solid → Gas

Melting and Boiling Point Melting point → the temperature at which a substance changes from a solid to a liquid Boiling point → the temperature at which a liquid boils, or changes from a liquid to a gas

Other Types of Physical Properties Color Odor Size Shape Texture Hardness Magnetic Phase of Matter Solubility Elasticity Motion Temperature Sound Taste Viscosity Metallic / Nonmetallic Luster Ductility Malleability Conductivity Compressibility Organic Inorganic Show magnet and iron fillings

Examples The front board is white. Table tops are a rectangle. The glass in the windows is an amorphous solid. The faucet is metallic. The globe is magnetic. The odor in the room is pleasant. The soil in the terrarium is organic. The fish tank water is not very viscous. The birds fly. (motion)

Chemical Properties Characteristics that describe its "potential" to undergo some chemical change or reaction by virtue of its composition

Chemical Properties Reactivity Combustibility Flammability

Reactivity The ability of two or more substances to combine and form one or more new substances

Flammability vs Combustibility Flammability – the ability of a substance to burn Combustibility - how easily something catches on fire
