MATTER AND MATTER PHYSICAL PROPERTIES

How can we use the knowledge of properties of matter to our benefit?

• To determine the best materials for a specific purpose, for instance, a building.

• To know how much a piece of something cost.

• To learn that the nonliving things are made of matter

• To establish the best design of a thing

What are physical properties?

• Are the prices of a material.

• It corresponds to qualities or characteristics of matter that can be detected using our senses or a measuring device.

• Physical properties are the characteristics of the things that belongs to a person.

• Are the costs, characteristics, and colors of the objects.

Every day, we use different objects for different purposes. These objects are made of different materials, such as metals, glass, plastics, ceramics, and fibers, which have different physical properties.

• TRUE

• FALSE

In order to choose the right material, we should ask ourselves some questions such as:

• Does this object need to be flexible or rigid?

• Should this object be able to withstand scratches?

• Should this object be the most expensive?

• Does this object need to be good-looking?

The flexibility of a material is its ability to

• Bend without breaking and return to its original size and shape after bending.

• The ability to withstand scratches

• The temperature at which it changes in state from solid to liquid

• A measure of how readily heat passes through a material.

Strength is

• The ability to return to its original size and shape after bending.

• The ability to support a heavy load without breaking.

• The measure of how readily the heat passes through a material

• The quantity of matter packed into a unit volume of a material

The...... of a material is a measure of how readily electricity passes through it.

The... of a material is the temperature at which it changes state from a liquid to a gas.

It is the quantity of matter packed into a unit volume of the material.

• Density

• Hardness

• Melting point

• Flexibility

Regarding Thermal conductivity, materials that do not allow heat to pass through them easily are called :

• Heat insulators

• Poor heat conductors

• Heat conductors

• Heat carriers.
