Properties of matter

Which of the following words would you use to describe the gears in the picture?

Words
Heavy	Light	Dark	Silver
Beautiful	Ugly	Useful	Hot
Cold	Smooth	Hard	Metallic

Matter can be detected and described by its properties.

For example, the objects in the painting can be soft or hard, weigh more or less, they are in different colours, the milk can be the same temperature as the room, colder or warmer.

The properties of matter are the qualities that can be measured.

Properties of matter can be grouped in different categories:

General and characteristic or specific.
Extensive and intensive.
Quantitative or qualitative.

Specific or characteristic properties are those that have a unique value and are specific for each type of matter. This can be used to identify matter. For example, a hardness value of 10 identifies diamond exclusively.

Look at the properties below and indicate whether they are:

Extensive or intensive.
General or specific.

The density of a sample of matter is 0.8 g/cm3 and its boiling temperature is 78 °C. Look at the table below and indicate which material it is.

Material	Density (g/cm³)	Boiling point (ºC)
Water	1	100
Alcohol	0.8	78
Oil	0.9	220
Helium	0.13	−269

Describing matter

Matter can be detected and described by its properties.

For example, the objects in the painting can be soft or hard, weigh more or less, they are in different colours, the milk can be the same temperature as the room, colder or warmer.

Properties

Properties of matter can be grouped in different categories:

Specific properties

Specific or characteristic properties are those that have a unique value and are specific for each type of matter. This can be used to identify matter. For example, a hardness value of 10 identifies diamond exclusively.

Density
This indicates the quantity of mass per unit of volume:
d = m/V
These three cylinders have the same mass. Iron and brass have similar density; aluminium is less dense. Lead is a very dense material, water is less dense and air is not very dense.
