Presentation transcript:

Properties Substance – matter that has uniform and unchanging composition Ex. Pure water has the same lack of taste, color, b.p., density, etc. It is always made up of hydrogen and oxygen Ex. Sodium Chloride (Table Salt) is the same throughout made up of Sodium Chlorine (NaCl)

Physical Property Physical Property - can be observed or measured without changing the identity of the substance. Ex. Observing and measuring the boiling point, density, color

Physical Properties Extensive (physical) property - depends on the amount of matter Ex. Mass, length, volume Intensive (physical) property- independent of the amount of matter Ex. Color, density, melting point, boiling point

Physical States of Matter Solid- definite shape and volume, particles tightly packed in fixed positions and can only vibrate. Liquid- definite volume, indefinite shape, particles can flow past each other-fluid. Gas- indefinite shape and volume. Particles move more rapidly with lots of space between them. Particles take up the volume and shape of the container.

Illustration of 3 states of matter Difference between gas and vapor vapor is a gaseous state of a substance that is a solid or liquid at room temperature Ex. Steam

Chemical Properties Chemical Properties- a substance’s ability to change to form new substances or ability not to. Ex. Iron Iron rusts when it reacts with oxygen in the air Iron does not react with nitrogen gas in the air

Physical Change Physical Change – a type of change that alters the physical properties of a substance but does not change its composition. Examples Crumpled Aluminum Foil Cutting Paper Breaking a crystal Boiling Water

Chemical Change Chemical Change – a process involving one or more substances changing into new substances (aka: a chemical reaction) Words to identify a chemical change Rust Tarnish Explode Ferment Oxidize Burn Corrode Rot

Chemical Change Chemical Reaction - the process in which atoms of one or more substances are rearranged to form a new substance.

Evidence of Chemical Reaction Color change Bubbling- gas was released Odor Temperature change (may be chemical or physical) Note: Energy is always involved in physical and chemical changes
