Plastics and Polymers

Polymethyl methacrylate (PMMA), commonly known by the brand name Plexiglas, is a synthetic polymer that tends to become harder as the number of carbon atoms in the polymer chain increases. This increase in chain length leads to a higher degree of crystallinity, which contributes to the material's strength and hardness.

Plastic bags are created from fossil fuels, specifically from refined crude oil. They are not biodegradable, so once created they pretty much hang around in the environment breaking into smaller and smaller pieces but never actually being broken down and reused. They are also often found as litter along roadsides and are a major problem in the world's oceans.wrong u out

Incidentally, paper bags aren't much better - they are made by cutting down trees. They can be recycled in some areas, but this is relatively uncommon and most people just throw the paper bags away too.

A more environmentally friendly option is to use old cloth bags instead - you can bring them to the store with you and use them thousands of times. They can be washed periodically to keep them clean, and when they are completely worn out they are often made of cotton so they will biodegrade.

Most foods are wrapped in plastic to prevent contamination, preserve freshness, extend shelf life, and protect against physical damage during transportation and storage. Plastic packaging also helps reduce food waste by maintaining quality and preventing spoilage.

A protein is an example of a polymer composed of amino acid monomers linked together by peptide bonds. This polymer structure allows proteins to carry out numerous functions in the body due to their diverse shapes and chemical properties.

Well, if you have a turtle as a house pet, then before allowing your pet to wonder around the house, check for any plastic materials that are out where he can reach it and put them away... duh. And if you are talking about a random turtle that u saw eating plastic, then you can't really do anything except for pick up the plastic. Can't really tell a turtle not to eat something, it won't exactly listen. -.-

To prevent turtles from eating plastic bags, we can help by reducing our use of single-use plastic bags, properly disposing of plastic waste, participating in beach clean-ups, and supporting legislation for plastic bag bans or regulations. Educating others about the harm plastic bags cause to turtles and marine life is also crucial in raising awareness and fostering change.

1% or less of all oil consumption goes toward making plastics, so it is a sustainable source. However, we also consume oil as fuel, and THAT is where oil becomes an unsustainable source. If we can move away from oil as a fuel, then oil becomes sustainable.

Spinning a ring of plastic around your waist is commonly referred to as "hula hooping" or "hooping". It's a fun and popular activity for exercise and entertainment.

Students are estimating the quantity of plastic bags disposed of in a landfill in a day by conducting research, data collection, and analysis. They may visit the site, gather information on daily waste disposal rates, and calculate the approximate number of plastic bags being discarded based on their findings.

Using too many plastic bags leads to environmental pollution as they take hundreds of years to decompose and often end up in oceans, harming marine life. They also contribute to carbon emissions during production and disposal, exacerbating climate change. Transitioning to reusable bags can help mitigate these impacts.

Cement is a commonly used binding material in construction, made from limestone and clay that hardens when mixed with water. Geopolymer is a newer alternative material that uses industrial by-products like fly ash or slag, activated by an alkaline solution, to create a similar binding effect. Geo polymers tend to have lower carbon emissions and higher strength compared to traditional cement.

The class of large organic molecules that include polymers is proteins, nucleic acids, and carbohydrates. Lipids are the fourth major class of large organic molecules, but they are not polymers.

Polymer clay should not be used to make food items that are intended for consumption as it is not safe to eat. However, you can create realistic-looking miniature food items like fruits, cakes, and pastries for decorative purposes. Just make sure to clearly label them as not edible.

If you are asking can plastic surgery cahnge the way your face looks then: yes,very much so. When you smile it wont look like a smile it'll look like lips or chceeks that cant move. Usually ALL plastic surgery makes whatever you are getting done look plastic. Except boobs(sometimes) and booty

The organic molecule used as motor fuel is hydrocarbons, specifically in the form of gasoline or diesel. In the production of plastics, hydrocarbons are used to create polymers such as polyethylene and polypropylene.

"plastic bags" in Spanish is "bolsas de plástico".

There are two types of plastic: thermosetting and thermoplastic.

Thermosetting plastics, such as Bakelite, use resins that are baked into their final form, usually in a mould. The chemical reaction of baking changes the resin so that it can no longer become fluid if reheated. These plastics cannot be "remolded", only powdered and put to other uses.

Thermoplatics (the bulk of plastic materials) use resins that are not baked in their moulds. Thermoplastics are heated until they flow, then cast into shape. Because they are only heated to flow temperature, no chemical reaction of heating occurs, and they can be re-moulded in a recycling process.

p.s. Bakelite is named for its inventor, Baekland, not because of its processing. True Bakelite is dark brown to black, so light-coloured "hard plastic" radio cabinets are *not* Bakelite - they are commonly Catalin, urea formaldehyde, or some other resin.

Plastic bags are used by retailers, grocery stores, and consumers for carrying goods or items. However, the widespread use of plastic bags has led to environmental concerns due to their impact on wildlife and ecosystems. Many countries and regions have implemented restrictions or bans on single-use plastic bags to reduce pollution.

Amygdalin is a monomer found in almonds but not in RNA. Amygdalin is a cyanogenic glycoside that gives almonds their distinct taste but is not a component of RNA, which is made up of nucleotides (adenine, guanine, cytosine, and uracil).

A collection of monomers is more disordered than polymers. More linked subunits in varied arrangements allows for more random movement, bond formations, and thus energy release. The entropy of a group of monomers is greater than a polymer of the same size.

A protein is a polymer of amino acids. Proteins are essential for the structure, function, and regulation of the body's tissues and organs.

No. Although there may be some very rare exceptions, plastics are made from oil. Those which are made from vegetable sources may be sustainable in very small quantities but as soon as food crops are replaced for bio oil-production on a large scale, they cease to be sustainable.

micro-organisms cannot break them down, so they may last for many years in rubbish dumps. However, it is possible to include chemicals that cause the polymer to break down more quickly. Carrier bags and refuse bags made from such degradable polymers are already available.

A special polymer is a type of polymer that possesses unique properties or functionalities compared to conventional polymers. These can include biodegradability, shape memory, self-healing, or conductive properties, among others. They are designed for specific applications where these specific properties are required.
