Physical Properties of Matter • allows us to identify the substance without causing a change in the composition of the substance • State • solid, liquid, gas • Colour • different for some materials • Lustre • metallic shine • Conductivity • ability to transmit electricity • Malleability (ductile) • bendable
Physical Properties of Matter • Viscosity • the resistance to flow • Melting/Boiling points • temperature to change state • Solubility • ability to dissolve in water • Density • the amount of mass in a given volume • Hardness • the ability to scratch or be scratched by other materials
Chemical Properties of Matter • describes how a substance interacts with other chemicals causing a change in composition • Corrosion and decomposition • breaking down chemicals • Combustion • ability to burn • pH • acidic or basic • Reactivity • with water and acids
