Other than their physical and chemical properties, some objects also have special properties, or those characteristics that are based on the objects’ internal structure. There are ten special properties: brittleness, buoyancy, ductility, elasticity, flexibility, hardness, malleability, porosity, solubility, and tenacity.

Brittleness

Glass is among the materials with the special property of brittleness, or the ability to break easily. Materials that break easily are called brittle.

Chalk and ceramics are two other materials that exhibit brittleness.

Buoyancy

An object that floats in water has buoyancy, or the ability of an object to float in a fluid. This property is shown by boats and corks.

The ability of an object to float or sink in water depends on its density. An object that has lesser density will float in water. But the material will sink if the material’s density is greater than that of the liquid.
