Class 8 Science – Synthetic Fibres and Plastic

Class 8 Science – Synthetic Fibres and Plastic

In this article, we will discuss Synthetic fibers and Plastics.
Synthetic Fibres
Man-made fibers are known as synthetic fibers. A synthetic fiber contains multiple units which are joined together to form a single unit called a polymer. The structure of a polymer can describe as resembling numerous beads on a string, with each bead representing an individual unit that is joined to other such units. The common synthetic fibers are Rayon nylon, acrylic, and spandex.
Nylon-It is the first true synthetic fibers. It was first produced in the early 1930s by the scientists at the DuPont Company from coal water and air
Properties of Nylon
  • It is elastic and does not lose strength even after repeated use.
  • It is lustrous and easy to wash.
  • It is waterproof.
Nylon is used for making socks, stockings, tents, umbrellas, parachutes, and tarpaulins. They are also used for making toothbrush, fishing nets, and strings of badminton and tennis racquets
Rayon– It is also called artificial silk. It is prepared from cellulose which comes from wood pulp.
Properties of Rayon
  • Absorbs sweat
  • Shiny and lustrous resembling to artificial silk
Rayon is used for making suits, jackets, scarves, ties, home furnishing and bandages
Polyester-It is a group of different synthetic fibers. The most commonly used polyester is Terylene. It is blended with natural fibers to improve its properties. Terry cot a blend of terylene and cotton has better absorbing power compared to others. Terylene blended with wool to make terry wool which warns in addition to all the characteristics observed in polyesters.

Magnetic and non-magnetic material Class 6 Science

Magnetic and non-magnetic material  Class 6 Science A magnet is a substance that is drawn to certain magnetic materials like iron, cobalt, and nickel. Magnets have the ability to draw iron to them. Natural magnets are rocks that naturally draw iron. Non-magnetic materials include things like wood, rubber, coins, feathers, leather, etc. that are not drawn to iron. Magnet characteristics It pulls magnetic materials, such as iron. The magnet's two ends are referred to as its poles. The magnet's diametrically opposed poles are drawn together. Heating, hammering, or dropping causes it to lose its characteristics. On the basis of properties types of Magnets Temporary magnets are those magnets that are magnetic for only a little duration. Typically, iron, cobalt, or nickel are used to make them. When they are close to the powerful magnet, they act like a magnet. When they are yanked away from the powerful magnet, they stop being magnetic. Permanent magnets are magnets that have magne...

What are Noble Gases? Example and noble gases name

What are Noble Gases? Example and noble gases name Noble Gases Noble gases, sometimes known as inert gases or erosions, are part of the modern periodic table's 18th group. This group is made up of the following individuals: Helium is a kind of gas (He) Neon (Ne) Argon is a gas (Ar) Krypton  (Kr) Xenon is a kind of xenon gas (Xe) Radon is a gas that can cause cancer (Rn) Noble gases exist in a gaseous state under typical temperature and pressure conditions. Because all noble gases have stable electronic structures, they have very little chemical reactivity. They are monoatomic gases that do not readily form molecules. 'ns2np6' represents the basic electrical configuration of noble gases. As a result, noble gases' outermost valence shells can be deemed 'complete.' The chemical inertness of the group of 18 elements is due to this. Because of the stability of certain elements, these gases form a group. These stable elements' crusts are totally filled.
