Physical and Chemical Changes and Properties © Carey Munoz © Carey Munoz You need four “flaps.” To cut “flaps,” cut only the top half of the folded paper. © Carey Munoz 1 2 3 There are four flaps of information. 4 Do not write these numbers on your flaps! Physical property A characteristic observed or measured without changing the composition; Often, you can use your senses to determine physical properties Chemical property Physical change Chemical change The ability of a substance to undergo a specific chemical change A change in matter which does not alter the chemical composition of the matter A change in which a substance (or substances) is changed into one or more new substances © Carey Munoz 1 9/3/2015 Under flap 1 – physical property Under flap 2 – chemical property 1 2 3 4 Examples 1 2 3 4 1 2 3 4 Examples •Color •Volatility •Flammable – or nonflammable •Solubility – or insolubility •Odor •Reactive – or unreactive •Taste •Hardness •Corrosive – or noncorrosive •Freezing Point •Viscosity •pH •Boiling Point •Texture •Combustible – or noncombustible •Melting Point •Opacity – opaque or transparent •Biodegradable or nonbiodegradable •Density •Luster •Magnetism •Conductivity – heat or electricity •Mass •Volume © Carey Munoz © Carey Munoz Under flap 3 – physical change Under flap 4 – chemical change 1 2 Examples 3 4 Examples •Dissolve •Evaporate •Decompose •Growth •Evolution of light •Melt •Inflate •Bake •Neutralization •Evolution of heat •Freeze •Crack •Develop Film •Rotting •Carmelize •Condense •Crush •Corrode •Digestion •Boil •Break •Combust •Electrolysis •Any change that forms new substances •Sublime •Distill •React •Oxidation •Split •Filter •Rust •Reduction •Absorb •Shred •Food spoils or •Cut •Tear •“Gas is liberated” (This occurs without heating) © Carey Munoz •Any Phase Change sours © Carey Munoz 2
