Which properties can be studied to group materials?

Given below are some properties of the materials that can be studied to group materials together.

Appearance: The look, feel, and texture in addition to lustre, colour and quality defines the property of the appearance of the material.

• Soluble/Insoluble: The nature of the material to completely dissolve in water is termed soluble material.

Eg: Lemon juice, Sugar and Salt.

Materials that don’t completely dissolve in water, form a thin film over the surface of the water termed insoluble material.

Eg: Oil, Kerosene and Sawdust.

• Hardness: materials that can be compressed easily are called soft. While the materials that can’t be compressed easily are called hard. 

Eg: the key is hard, and cotton is soft.

• Float/Sink: The weight of the material helps to define this property. If the material is lightweight, it will float over the surface, therefore, is called floating material.

Eg: Sawdust, Oil, Plastic and Wood.

The material is heavyweight and it will sink in water. 

Eg: Stone and Metals

• Transparency/Opaque: The amount of light material allowed to pass through a material is the transparency of the material. The maximum amount of light to pass through the material, therefore, are transparent materials.

Eg: Plastic, Air, and Glass.

• Translucent materials are, which only allow light to pass through them partially.

Eg: Oiled paper, Coloured syrup, and some sheer materials. 

• An opaque object is a material, which doesn’t allow any light to pass through them. 

Eg: Wood, Cardboard, and Metals.
