Explanation

Polythene is a thermoplastic because it softens when heated and can be reshaped.

It is formed by polymerization of ethene molecules.

Explanation

PVC, or Polyvinyl Chloride, is a widely used synthetic plastic polymer.

It commonly found in pipes, cables, and other construction materials due to its durability and flexibility.

Explanation

• Plastic is a synthetic material that is resistant to decomposition and can take hundreds or even thousands of years to break down.
• It is a non-biodegradable material.

The examples of non-biodegradable materials such as:

• Inorganic materials (glass, ceramics, heavy metals)
• Synthetic materials (styrofoam, plastic bags, other plastic things)
• Hazardous materials (detergents, toxic chemicals)
• Industrial waste (empty cans, electricity wires, fused bulbs, broken machine parts)

Explanation

International Plastic Bag Free Day is celebrated every year on July 3 to create awareness of the adverse effects of the use of a single plastic bag on the environment.

Explanation

Plasticine was invented in 1897 by William Harbutt, an English artist and teacher.

It is a soft, oil-based modeling material used widely in art and education.

Explanation

Plastic was invented in 1907 by Leo Baekeland.

He created Bakelite, the first synthetic plastic, which marked the beginning of the modern plastics industry.

Explanation

In 2002, Bangladesh became the first country in the world to ban plastic bags after they were found to block drainage systems and cause severe flooding.

The ban was implemented to combat environmental pollution and protect urban infrastructure, especially in Dhaka.

Explanation

In an optical fiber, the core is made of a material with a relatively high refractive index, typically glass or plastic with a high refractive index.

This allows the light to be confined and transmitted through the fiber via total internal reflection.

The cladding surrounding the core has a lower refractive index, which helps to keep the light within the core.

Explanation

Polyethene, also known as polyethylene, is a type of plastic.

It is a thermoplastic polymer made from ethylene monomers.

It is commonly used in packaging, plastic bags, and containers.
