howareplastics diffrent and similar to metals and glass?

It's depends the way you formulate the composition of plastics.These days ABA/ABS is similar to metals and glass.Some composition of polyurethane are also like metals and as transparent as like Glass.Say for example Bakelite which we used in electrical fuses and switches which replace metal as well as providing us security of electrical shocks.

A note on recyclability . . . \n\nFor food products in the US, recycled plastic must be depolymerized (broken down into component cheicals and no longer be a plastic), then repolymnerized to be used in food-safe applications. This is not the case if one uses recycled plastic to make fabric, or for use in non-foodsafe applications. The capital cost of the plant and energy involved in depolymerizing and repolymerizing the plastic make recycled plastic prohibitively expensive for foodsafe applications.

Metal.  Wood and plastic can crack.

plastic is not degradable and if left on the earth would eventually choke the earth, plastic if burnt there is air polution plastics can be recycled but eventually it has to be destroyed, animals have been know to accidently eat plastic, small children usually put plastic toys in their mouth which if of a cheap quality can harm babies, plastic bags in the hands of small children,  can suffocate them if they playfully put it over their heads

Because if it is made of plastic, Plastic is a product of petroleum.\n\nYou will probably be surprised to know that a plastic bottle is made from the same petrochemical as the fiber we call polyester!\n\nAll plastic products, many of the materials used to make the clothes you wear, or the carpet you walk on, plus hundreds of the other products we take for granted, are made from petrochemicals. As the name implies, a main ingredient in petrochemicals is oil. \n\nPlastic: Any of various complex organic compounds produced by polymerization, capable of being molded, extruded, cast into various shapes and films, or drawn into filaments used as textile fibers. \n-- Webster's Dictionary\n\nThat's an interesting definition, you may be thinking, but really -- how is plastic made? What's involved in the plastics manufacturing process? \nThe Basics of Plastic Manufacturing \n\nThe term "plastics" encompasses organic materials, such as the elements carbon (C), hydrogen (H), nitrogen (N), chlorine (Cl) and sulfur (S), which have properties similar to those naturally grown in organic materials such as wood, horn and rosin. Organic materials are based on polymers, which are produced by the conversion of natural products or by syththesis from primary chemicals coming from oil, natural gas or coal. \n\nThe plastic manufacturing process begins by heating the hydrocarbons in a "cracking process." Here, in the presence of a catalyst, larger molecules are broken down into smaller ones such as ethylene (ethene) C2H4, propylene (propene) C3H6, and butene C4H8 and other hydrocarbons. The yield of ethylene is controlled by the cracking temperature and is more than 30% at 850°C and such products as styrene and vinylchloride can be produced in subsequent reactions. These are then the starting materials for several other types of plastics. Therefore, this process results in the conversion of the natural gas or crude oil components into monomers such as ethylene, propylene, butene and styrene. \n\nThese monomers are then chemically bonded into chains called polymers. Different combinations of monomers yield plastic resins with different properties and characteristics. Each monomer yields a plastic resin with different properties and characteristics. Combinations of monomers produce copolymers with further property variations. \n\nThe resulting resins may be molded or formed to produce several different kinds of plastic products with application in many major markets. The variability of resin permits a compound to be tailored to a specific design or performance requirement. This is why certain plastics are best suited for some applications while others are best suited for entirely different applications. For instance, impact strength measures the ability of a material to withstand shock loading. Heat resistance protects the resin from exposure to excessive temperatures. Chemical resistance protects the resin from breakdown due to exposure to environmental chemicals. \n\nSome examples of material properties in plastic product applications are: \n\nHot-filled packaging used for products such as ketchup \nChemical-resistant packaging used for products such as bleach \nImpact strength of car bumpers \n\nThe Structure of Polymers \n\nPolymers are created by the chemical bonding of many identical or related basic units and those produced from a single monomer type are called homopolymers. These polymers are specifically made of small units bonded into long chains. Carbon makes up the backbone of the molecule and hydrogen atoms are bonded along the carbon backbone. \n\nPolymers that contain primarily carbon and hydrogen are classified as organic polymers. Polypropylene, polybutylene, polystyrene and polymethylpentene are examples of these.\n\nEven though the basic makeup of many polymers is carbon and hydrogen, other elements can also be involved. Oxygen, chlorine, fluorine, nitrogen, silicon, phosphorous and sulfur are other elem

both will have a miniscus and this is due to the adhesive property of water. the cohesive property keeps the water molecules togherter but the adhesive props allow for movement as in a cappilary tube. the gLass is clearer than the plastic so im thinking glass

Mostly they use Isoproyle butane... not harmful to plastic.

Precede is incorrect to say that ALL plastics are petroleum based. \n\nMost plastics you will encounter are petroleum based - think your coca cola soda bottles, toothbrushes, tupperware containers, the lids of McDonalds soda cups, straws.... the list is very long - simply because they are, and have been for some time, cheap to produce.\n\nThey are very bad for the environment since most of what is produced ends up in landfills. It also isn't a very logical process since a lot of the goods made out of these plastics are containers (like soda bottles) that are used once, then thrown out thus not needing the durability or shelf life that plastics have.\n\nThere is a growing field of science called biopolymers, and a growing market for bioplastics. While this word isn't yet recognized by Microsoft Word, it is often used to describe plastics that biodegrade much faster than petroleum based plastics (think days, on the range of 30 under the right conditions,  as opposed to decades). These plastics are made out of things like corn and/or bagasse (sugar cane derivative). One retailer I know of is World Centric (google them). We bought their plastic cups for a fundraiser recently and you can't even tell the difference! \n\nIt would be interesting to know how much energy it takes to produce these petroleum alternatives and compare it to that of the petroleum plastics.

Plastic state.  \n:-) Hope this helps!

Do you mean supercooled substances?\n\nIf so, glasses are the best example and are made by melting a salt and quickly cooling it so that it does not return to its original form.  I don't believe you should have any trouble pointing out the various contributions of glass to our lives.

The answer is glass... glass is an amorphus solid, meaning that it has solid characteristics, but is technically "flowing"

First of all, polymers are considered blends of different plastics to fit a certain usage.\n\nThermoplastic, from its name, tells us that these plastics can withstand extremely high and low temperature, so such plastics may be used for cooking and/or other things like containment of highly reactive materials.\n\nVOTE FOR BIG LINH HE NEEDS POINTS :P

There are thousands of polymers all with very different chemical and physical properties.  so a simple answer can not be given.  perhaps a specific polymer would obtain better responses.

METALS ARE MALLEABLE AND DUCTILE INDEED THEY ARE VERY STRONG SOME METALS LIKE ALUMINIUM HAS A LOW DENSITY SO IT'S USED IN BUILDING AIRCRAFTS,IOW DENSITY COOKING UTENSILS ETC.. ALLOYS EG:STEEL IS ALSO USED IN UTENSILS ....COINS ARE ALLOYS OF NICKEL AND COPPER.....METALS USUALLY HAVE A HIGH MELTING POINT.......

Glass is composed of mainly silicone, heated to a high temperature until it forms a supercooled liquid. Sand is the most common form of raw material used in making glass though silica is sometimes used. Other materials can be added in to give extra strength or changes in its composition to make specialized products such as pyrex, coloration and certain metals are added to add colour to it.
