3. Background: Physical Chemical Properties Definition
Examples of Properties
Change Definition
Examples of Change
Can be determined without seeking a chemical reaction. It is a quality or trait that describes a material or object
Can only be determined by adding another chemical to see if a reaction occurs
Color
Hardness
Texture
Light transmission
luster
Reaction with hydrochloric acid (HCL)
A physical change occurs when a substance changes its state (solid, liquid, gas) or when it is broken into smaller pieces or combined into larger ones.
A change in how atoms or molecules are bonded to each other, resulting in a new arrangement of atoms or molecules. A chemical change always results in changed physical properties
Iron rusting
An acid dissolving a metal
Wood burning
An egg becoming hard boiled
Cut/smash/fold
Evaporate/boil
