Examples of Physical Properties

Introduction on Examples of Physical Properties:

Physical properties are the properties that can be observed without changing the identity of the substance. In other words,physical properties are the properties which describe a substance without changing its chemical composition. The general properties of matter such as density, colour and hardness and  Melting point, boiling point, thermal conductivity, ductility, malleability are also the examples of Physical properties. I like to share this Specific Gravity Formula with you all through my article.



Some Examples of physical properties:


Density

It is a physical property of matter. Each compound and element has its unique density associated with it. In qualitative manner, density is defined  as the measure of the relative "heaviness" of objects with a constant volume.

Melting point

Melting point is referred as  the temperature at which the solid and liquid states of a pure substance can exist in equilibrium position.If the heat is applied to a solid, its temperature increases till it reaches the melting point. At this temperature, the additional heat converts the solid into  liquid without a change in temperature.

Boiling point

The temperature at which a substance changes from liquid state to gaseous state is  referred as boiling point.If the pressure of the surrounding gases is decreased, the boiling point of a liquid is lowered. Usually, water will boil at a lower temperature at the top of a mountain, since the atmospheric pressure on the water is less, than it will at sea level, where the pressure is greater.

Other Examples of Physical Properties


Thermal conductivity

Thermal conductivity is an intrinsic property of a material which has the ability to conduct heat. In general,heat transfer by conduction involves transfer of energy within a material without any motion of the material . In a solid medium, conduction takes place when a temperature gradient exists.

Ductility

Ductility is the property of metal which permits it to be reduced in cross sectional area without fracture. Usually ductile metals show considerable elongation eventually failing by necking, with consequent rapid increase in local stresses during the tensile test.
