Answer:
Materials are most of all the objects and therefore materials have its own properties. In general different properties of materials are enlisted below. Since materials have these properties it makes the materials useful and purposeful to use. To understand the properties of material explore the article!The material can be termed as the mixture of materials to compose a thing.
Properties of Materials
Transparency/Opaque: The amount of light material allow passing through it is transparency of the material. The maximum amount of light to pass through the material, therefore, they are transparent materials. Examples: Plastic, Air, and Glass.
Translucent materials are, which that only allow light to pass through them partially. Examples: Oiled paper, Coloured syrup, and some sheer materials. An opaque object is the materials are, which don’t allow any light to pass through them. Examples: Wood, Cardboard, and Metals
The appearance of the Material: The look, feel, texture in addition to lustre, colour and quality defines the property of appearance of the material.
Soluble/Insoluble: The nature of the material to completely dissolve in water and therefore termed as soluble material. Materials are completely dissolvable in water, therefore, they are soluble materials. Examples: Lemon juice, Sugar and Salt. materials don’t completely dissolve in water, they form a thin film over the surface of the water, therefore, they are iron rods and copper wires.Examples: Oil, Kerosene and Sawdust.Float/Sink: weight of the material helps to define this property. The material is lightweight it will float over the surface, therefore, they are floating material. Examples: Insoluble materials like Sawdust, Oil, Plastic and Wood. The material is heavyweight it will sink in water, therefore, they are sinking materials. Examples: Stone and Metals
Heat and electricity conductivity: Materials that allow heat and electricity pass through the material and hence called good conductors of heat and electricity. Good conductor of heat and electricity are which allow the head and electricity pass through them.Examples: Iron rods and copper wires. Bad conductors are the materials which don’t allow heat and electricity pass through them. Examples: hydrochloric acid.
State of a material: Compactness and the consistency of the materials describe the state of a material. There are 3 states in which a material can be classified and they are as solid, liquid and gaseous. Solid materials are the most compact and the particles are densely packed.
Examples: Wood, Paper and Glass. Liquid materials are less compact and particles are moderately densely packed. Examples: Water, Oil and Kerosene. Gaseous materials are least compact and particles are loosely packed. Examples: Air.

Answer:
Objects are grouped on the basis of properties like lustre, hard/softness, transparency, solubility, floatation, attraction towards magnet, conduction of heat and conduction of electricity. Property - Lustre: Materials can be grouped as lustrous and non-lustrous on the basis of lustre/shine possessed by them.
