Options (8)

Odor

Melting Point (temp at which a solid turns to liquid)

Brittleness (ability to break/shatter)

Luster (shininess)

Reactivity (tendency to react with other substances)

Flammability

Acidity/pH

Conductivity (Ability to conduct heat)

Categorize the following as chemical or physical properties. Remember: Physical properties can be observed without chemically changing a substance and chemical properties require a chemical reaction in order to be observed
