What are the differences between polymers and plastics?
Polymers are large molecules made up of repeating units, while plastics are a type of polymer that can be molded into various shapes. Not all polymers are plastics, but all plastics are polymers. Plastics are a subset of polymers that have additional properties, such as being lightweight, durable, and easily molded.
Why do natural polymers not pose as much of an issue in landfills as synthetic polymers Natural polymers are cheap to recycle and synthetic polymers are expensive to recycle. Natural polymers are expe?
Natural polymers are biodegradable, meaning they can be broken down by bacteria and other organisms in the environment. This process helps to reduce the amount of natural polymers going to landfills. Synthetic polymers, on the other hand, are not easily biodegradable and can persist in the environment for a long time, contributing to landfill waste issues.
How are natural polymers and synthetic polymers similar?
Rubber is a natural polymers with elastic and plastic type behavior. It is found in nature and extracted from trees. PET (soda bottles) Polyethylene Terephthalate is a synthetic polymer and not found in nature.
What do the big six polymers have in common?
The big six polymers (polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyethylene terephthalate, and poly(methyl methacrylate)) are all synthetic polymers derived from petrochemicals. They have a wide range of applications due to their versatility, durability, and low cost. Additionally, they are all thermoplastic polymers, meaning they can be melted and reshaped multiple times.
What are moldable materials?
Moldable materials are substances that can be shaped or formed into desired shapes or structures. This includes materials like clay, playdough, plasticine, and certain types of polymers or resins that can be molded and shaped by hand or using molds. These materials are often used in crafts, modeling, prototyping, and 3D printing.
Why are synthetic polymers often used in place of natural material?
Synthetic polymers are cheaper than natural polymers. Natural polymers are also less plentiful.
How is the polymer classified?
For example thermoplastic and thermosetting polymers, natural and synthetic polymers.
Is there any subgroups of polymers?
Yes, polymers can be broadly categorized into natural and synthetic polymers. Synthetic polymers can further be classified based on their chemical structure and properties, such as thermoplastics, thermosets, elastomers, and fibers. These classifications help in understanding the different characteristics and applications of polymers.
What are some macromolocules?
Macromolecules are polymers. There are bio-polymers such as carbohydrates, proteins, lipids and DNA, and there are synthetic polymers such as plastics (polystyrene and polyvinylchloride) and synthetic fibres. Nylon and terylene are also considered macromolecules.

Are cellulose molecules examples of synthetic polymers?
No, cellulose molecules are not examples of synthetic polymers. Cellulose is a natural polymer found in the cell walls of plants and is composed of repeating glucose units. Synthetic polymers, on the other hand, are man-made polymers created through chemical processes.
Is a xylophone molded or carved?
It depends on the material. Wooden xylophones are carved, while synthetic ones are molded.
What is the difference between a bio-polymer and a synthetic polymer?
Bio-polymers are derived from renewable resources, such as plants and animals, and are biodegradable, while synthetic polymers are man-made from fossil fuels and are not biodegradable. Bio-polymers have a lower carbon footprint and are more environmentally friendly compared to synthetic polymers.

How are nature polymers and synthetic polymers similar?
Nature polymers and synthetic polymers are both large molecules made up of repeating units called monomers. They both have high molecular weights and exhibit similar properties like flexibility, strength, and durability. Additionally, both nature and synthetic polymers can be engineered to have specific properties for various applications.
What state of matter can be molded or shaped?
As solid
