Explanation:
When we refer to the properties of a material, we are talking about features we can sense, measure or test. For example, if we have a sample of metal in front of us, we can identify that this material is grey, hard and shiny. Testing shows that this material is able to conduct heat and electricity and that it will react with an acid. These are some of the metal’s properties.
Zinc
Zinc is a chemical element found in the Earth’s crust.
It is important to decide if you are investigating the properties of a material or of an object. For example, are you identifying the properties of a spoon (an object), or are you looking at properties of the material it is made of, for example, stainless steel? Properties like shape and mass may be different for different objects, even when they are made of the same material. Density is a useful property for making comparisons between different materials.
Spoon
This spoon is made from stainless steel. This material was selected based on its physical and chemical properties.
Use this activity to learn more about density.
Other properties of materials can include their viscosity and conductivity.
A commonly talked about property is the state or phase of matter. There are currently five different states of matter that have been identified: solids, liquids, gases, plasma and Bose-Einstein condensate. The last two of these are much less well known.
It is important to note that the state of matter refers to the positioning and movement of the particles that make up a material and not the material itself.
You can learn more about states of matter in the article States of matter.
