Polymers a long chains of monomers, and the interaction between the molecules are weak Van der Waal's forces. In metal, they exists as cations (positively charged ions) in a "sea" of delocalised electrons, hence the intermolecular interaction is the much stronger electrostatic forces.
Imagine taking 5 sheets of thick paper stacked on top of each other, it is easier to bend them compared to 5 magnetic strips, as it requires less forces to overcome the weak Van der Waal's forces exemplified in the paper rather than the strong electrostatic forces exemplified in the strips of magnet
Mostly cost. The material is less expensive than metal, it's less expensive to form it into the finished product because most plastic parts are molded, and you can get polymer closer to final form in the molding stage than you can metal. Also, there are transparent polymers and, Star Trek notwithstanding, metal is very opaque.
Today's product is a gas tank for a car. A gas tank is an enclosed box with a neck to fill it through, a big hole in the top surface for the fuel pump with a reinforcing ring around it, and six threaded bolt holes around the big one so you can secure the pump to the tank. If you were to make it from metal, you'd first stamp out the top and bottom halves. You'd cut holes in the top for the neck and pump, then weld on the neck and reinforcing rings. The bolt holes would then be drilled and tapped. After welding the two halves together, you would have the tank galvanized so it won't rust, painted, and sometimes internally coated. If you were going to make the same tank from polyethylene, the mold would produce a one-piece tank with the neck and pump hole already in place and the bolt holes where they are supposed to be...and the only work you'd have to do to the tank to get it ready for use is to trim the plastic away from the neck and pump holes.
The advantage of using metal over polymer (not composites, but pure plastic) is that for the same strength the metal weighs less, you can repair metal easier than plastic assuming that you can repair plastic at all, and it's more reliable in that it's stronger and it fails in a more gradual fashion. Plastic has taken over the market for gas tanks on passenger cars, but you'll never see a plastic tank on a race car, a big truck or an aircraft.
This is due to the cross linking in the Polymers, (Rocket stop cheating)
Polymers are cheaper, resistant to corrosion and have a low density.
Cryogenic Processing of metals (i.e. metals frozen to low temperatures) show more resistance to wear
The disadvantage is that you can't destroy heavy metals (or any metals or, indeed, any chemical elements) by incineration. So the most you can achieve by incineration is scattering heavy metals around with ash that is carried away with smoke.
Predominantly transition metals.
what are some advantages to the Mercalli rating procedure
There are no particular advantages. A column is Excel is a vertical arrangement of cells.
Cryogenic Processing of metals (i.e. metals frozen to low temperatures) show more resistance to wear
It helps to separate metals from other rubbish such as paper and plastic.
hey paiges lol hailee -xx-
There are many possible advantages of using scent to attract a mate. One advantage is that you know they're compatible.
Africa
It is less expensive and safer ,particularly for early trainig
advantage and disadvantage of using cd-rom to get information about encyclopedia rather than internet
Virtually all synthetic polymers are used in industry.
Concrete is cheaper. As in cheaper per kilogram, cheaper to "model". Has a relatively high compressive strength
duffer idiot if i knew the answer i would not ask the question..................
Asbestos and polymers which make up the diaphragm are readily abundant and cheap and make the production of chlorine by the diaphragm method an economically advantageous process.
