Why are alloys produced? How does galvanizing prevent corrosion? Give an example. Briefly explain the industrial applications of fractional distillations. Why do metals tend to be malleable? Briefly explain how the conduction of electricity takes place in iron metal. ...
How are alloys made and what properties do they have? Why do metals tend to be malleable? Which alloy of aluminum is used for making magnet? Describe the metallurgy of gold. Why metals cannot be charged by rubbing? Which is more active: iron or silver? Explain. ...
How brass is made? Is brass resistant to corrosion? What advantages does riveting have over spot welding for: a) Lot size of five? b) Lot size of ten thousand? (State three) How does solidification of alloys differ from solidification of pure metals?
We can use it to make things rust-resistant, for example, to produce a variety of useful alloys like brass and bronze, and even to make plastic look like metal. How does this amazing process work? Let's take a closer look!Photo: Electroplating in action—an exhibit at Think Tank (the...
But if it's made of a special kind of material called a shape-memory alloy, it doesn't actually forget that it's spoon shaped, and if you heat it up again it will magically spring back into its original shape! Shape-memory alloys are probably best known as the magic materials behind ...
Why are bridges not made from stainless steel? Compare electricity conductivity of copper and aluminum and give the reason for your answer. Starting with copper metal, describe how a sample of crystals of copper...
Why are alloys produced? Recrystallization is a product purification technique that is commonly used in many organic chemistry labs. Explain the theory behind recrystallization; that is, how does it function to purify a compound? Isoprene and terpenes are...
Explain how alloying changes these pure metals to make alloys How does mining cause erosion? Why is coal not classified as a mineral? What is the importance of chemistry in geology? Why are basalt and granite important igneous rocks? How can metamorphism change sulfide minerals? Why are fossil...
The amazing thing is that both these radically different materials are made of identical carbon atoms. So why is graphite different to diamond? The atoms inside the two materials are arranged in different ways, and this is what gives the two allotropes their completely different properties: ...
If you think of how a long coal train is made from many trucks coupled together, that's what polymers are like. The trucks are the monomers and the entire train, made from lots of identical trucks, is the polymer. Where a coal train might have a couple of dozen trucks, a polymer ...
