Physical Property Characteristic of a pure substance that can be observed WITHOUT changing it into another substance.
Physical Properties of Matter It does NOT CHANGE into something else Examples color shape taste state/phase density D = m V
Physical Change a change in shape, size, color, or state a change without a change in chemical composition a change that is reversible The Mixtures Lab Examples tearing paper cutting your hair change in state
Page 29 Chemical Property A characteristic of a pure substance that describes its ability to change into a DIFFERENT substance.
Chemical Properties of Matter changes into a new substance Examples flammability reactivity with vinegar reactivity with oxygen Iron + Oxygen Iron oxide (rust) 2Fe + 3O2 Fe2O3
combining sulfuric acid and sugar Chemical Change a change in which a substance becomes another substance having different properties a change that is not reversible using ordinary physical means Changes that usually cause heat, sound, light, odor, fizzing/foaming, color changes Examples combining sulfuric acid and sugar burning a piece of wood soured milk Salt: http://www.schooltube.com/video/2fa9cb3e39064832b31d/Reaction-of-Sodium-and-Chlorine
Chemical or Physical Property? Paper is white Boiling point of H2O is 100oC Zinc reacts with hydrochloric acid and creates hydrogen gas Nitrogen does not burn Sulfur smells like rotten eggs Physical Property Physical Property Chemical Property Chemical Property Physical Property
I.S. Learning Goal: I can describe predict properties of elements and compounds using trends of the periodic table (e.g., metals, non-metals, bonding – ionic/covalent).
Comparing Physical and Chemical Properties Substance/Matter Physical Property Chemical Property Helium Less dense than air Nonflammable Wood Grainy texture Flammable Baking soda White powder Reacts with vinegar to produce bubbles Powdered sugar Does not react with vinegar Rubbing alcohol Clear liquid Red food coloring Red color Reacts with bleach and loses color Iron Malleable Reacts with oxygen
Chemical or Physical Change? Bending a Paper Clip Baking a cake The sublimation of carbon dioxide Crushing an aluminum can Vinegar and baking soda combining to create salt and water Physical Change Chemical Change Physical Change Physical Change Chemical Change

4 Physical States of Matter Solid Liquid Gas Plasma
Solid Particles are tightly compact Particles vibrate without the ability to move freely Definite shape and volume Solid Animation
Liquid Particles are tightly compact, but able to move around close to each other No definite shape, but definite volume Liquid Animation
Gas Particles can easily spread out or move close together Particle move freely and with a lot of energy No definite shape or volume Gas Simulation
Plasma Why do you think this is the most common form/state of matter in the universe? Exist at extremely high temperatures (several million degrees Celsius) Particles are broken apart Particles move freely and with extremely high energy This form is not too common on Earth, however it is the most common form of matter in the universe No definite shape or volume (?) Examples: Florescent and neon lights, lightning, aurora borealis - + + + - -
