Physical Properties
Hardness A measure of the
resistance of a solid to being scratched
Eg. Diamond is hard and chalk is soft
Physical Properties
State Is the substance a
solid, liquid or gas at room temperature
Eg. Metal is solid, milk is liquid and helium is a gas
Physical Properties
Malleability The ability to be
hammered or bent into different shapes
Eg. Aluminum is malleable and glass is brittle
Physical Properties
Ductility The ability to be
pulled into wires Eg. Copper is
ductile and coal is not
Physical Properties
Melting Point & Boiling Point
M.P. when a solid turns into a liquid & B.P. when a liquid turns into a gas
Eg. Water at 0°C & 100°C
Physical Properties
Crystal Form Solid mineral
structure with a regular pattern of 3D shapes
Eg. Salt is crystal but plastic is not
Physical Properties
Solubility The ability to
dissolve in a solvent such as water
Eg. Salt is soluble in water and pepper is not
Physical Properties
Viscosity A measure of
how easily a liquid flows
Eg. Maple syrup is more viscous than milk
Physical Properties
Density The amount of
matter per unit volume of substance
Eg. Lead is more dense than feathers
Chemical Properties
Combustibility The ability to
react rapidly with oxygen and release heat and light energy
Eg. Gasoline is combustible and water is not
