What is a property of a material?
A property is a describing word that tells you what a material is like.
Every material around you can be described with words. Glass is transparent and brittle. Rubber is flexible and waterproof. Steel is hard and strong. Each of these describing words is a property.
A property is a word that tells you what a material is like or how it behaves. Properties are how scientists compare materials and decide which one is best for a job.
It helps to sort properties into groups. For example:
- How it feels and looks β rough or smooth, shiny or dull, see-through or not.
- How it behaves β does it bend, snap, float, conduct heat?
The same material always has the same properties. Wood is always less dense than steel; glass is always brittle. Because properties are reliable, you can predict how a material will behave before you even use it.
Knowing the properties of materials is the first step to choosing the right one β which is what this whole topic is really about.
- A property is a word describing what a material is like.
- Properties tell you how a material looks, feels and behaves.
- The same material always has the same properties.
- Knowing properties lets you predict how a material will behave.
