Physical Properties • Physical properties can be determined without changing the identity of the substance. • Examples???
Viscosity • Resistance to flowing Maple Syrup- High Viscosity Water- Low Viscosity
Ductility • Ability to be drawn into a thin wire
Malleability • Ability to be hammered into thin sheets without shattering
Hardness • A substance’s resistance to being scratched
Solubility • Ability to dissolve in water • Yes! It is a physical property because you do not need to alter identity of the substance to determine solubility.
Conductivity • Ability to carry electricity Superconductor? Semiconductor?
Other examples of physical properties…. boiling point shape density freezing point melting point temperature
Chemical Properties • Describe the way a substance can change or react to form other substances. • Must be determined using a process that changes the identity of the substance
