9. Physical vs. Chemical Properties Physical can be observed without a chemical change- you can look, measure or touch can be observed without a chemical change- you can look, measure or touch Freezing, boiling, melting, and other changes of state Freezing, boiling, melting, and other changes of state Floating or sinking Floating or sinking Shine (luster) Shine (luster) Magnetic or not Magnetic or not Brittle (breaks) or bendable Brittle (breaks) or bendable Color Color From Activity 6- appearance, ability to mix From Activity 6- appearance, ability to mix From Activity 7- conductivity, relative density From Activity 7- conductivity, relative density

10. Chemical Properties how a substance changes into different substances through a chemical reaction how a substance changes into different substances through a chemical reaction Flammability Flammability Reacts: example, rusts or corrodes Reacts: example, rusts or corrodes Change in the presence of another chemical to a new substance Change in the presence of another chemical to a new substance From Activity 6- pH, test for toxicity (reacts with potassium solution to make a red solution) From Activity 6- pH, test for toxicity (reacts with potassium solution to make a red solution) From Activity 7- corrosiveness From Activity 7- corrosiveness
