The specific properties of matter are characteristics that identify and describe it at a more detailed level:
Density: Mass per unit volume; how tightly packed particles are.
Elasticity: Ability to deform and return to original shape.
Luster: Shine or reflectivity of a surface.
Hardness: Resistance to deformation or scratching.
Temperature: Measure of thermal energy in a substance.
Viscosity: Resistance to flow in a liquid.
Melting point: Temperature at which a solid becomes a liquid.
Boiling point: Temperature at which a liquid becomes a gas.
Malleability: Ability to deform without breaking.
Ductility: Ability to stretch into a wire.
Conductivity: Ability to conduct heat or electricity.
Solubility: Ability to dissolve in a solvent.
