Learn about the difference between physical and chemical properties of substances and how they can be observed. Discover the various properties such as state, luster, density, solubility, malleability, ductility, heat conductivity, melting point, boiling point, flammability/combustibility, reactivity with an acid, and oxidation.

What is a property? • Property: a characteristic of a substance that can be observed
Physical Property A property that can be observed without changing the substance.
Malleability • Substance’s ability to be hammered into a thin sheet
Ductility • Substances ability to be stretched into a wire.
Melting Point • Melting point: the temperature at which a substance changes from a solid to a liquid
Boiling Point Boiling point: the temperature at which a substance changes from a liquid.
Chemical Properties • Properties that can only be observed by changing the substance.
