Study Notes

Sorting Materials into Groups

Materials refer to specific samples of matter, while substances are more specific, classified as either pure elements or pure compounds.
Lustre describes the shine or sheen on the surface of a material or substance.
Transparency indicates a material's ability to allow light to pass through.
Insulators are materials that do not conduct heat or electricity, making them useful for preventing energy loss.
Grouping involves organizing similar materials or substances together for analysis or usage.

Objects Around Us

Nonliving things can be categorized as either natural or man-made, which include everyday items like chairs, tables, cupboards, almirahs, clothes, refrigerators, cooking ranges, utensils, crockery, cars, scooters, aeroplanes, and trains.

Common Characteristics of Materials

Materials can include wood, glass, and textiles such as cotton, synthetic fibers, and jute.
Building materials like clay and cement are also commonly used.

Important Properties of Materials

Metals, plastics, and paper each exhibit distinct physical and chemical properties that influence their applications and usefulness in various contexts.

Other Interesting Properties of Materials

Materials are organized into groups based on their characteristics, such as their physical properties, chemical composition, and how they react under different conditions.
