1 Activity 14 Title: Physical and Chemical Properties of Materials

2 Read B-14 Challenge: How do the properties of materials determine their uses? Hypothesis/Initial Thoughts:

3 Background: PhysicalChemical 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 Color Hardness Texture Light transmission luster 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. Cut/smash/fold Evaporate/boil Can only be determined by adding another chemical to see if a reaction occurs Reaction with hydrochloric acid (HCL) 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
