How is an alloy used?
An alloy is used where a pure metal is not sufficient. As an example, the superstructure of an aircraft is aluminum. By itself it is too soft and does not have the correct properties. So Aluminum is usually alloyed with a small amount ( 2- 3% ) of copper. This makes an aerospace alloy that is extremely useful.
Why are pentdents made from pewter?
pewter is a good metal to make a pendent with as it is an alloy metal (a metal made up from other metals) so it will have the different properties. its is easily melted and can be poured into molds of whatever the artist makes, so its much easier to play with than say silver or nickel.
How does a metal halide ballast work?
A metal halide ballast works just by transforming the line voltage into much more useful voltage to the metal halide, and by regulating the current so that the bulb will have its useful life at the most.
Why is argon has their uses?
Almost all elements have some properties which are useful and so they can be used for that purpose.
Why is iron so useful?
because it is a hard metal that can only be moved by heat or fire.
What is so special about iron that makes each iron atom a tiny magnet?
Iron atoms have unpaired electrons in their outer shell, allowing them to align in the same direction. When many iron atoms align in the same direction, they create a magnetic field. This alignment happens naturally due to the magnetic properties of iron.
2. Which property of plastics makes them so useful but also makes them environmental hazard?
it is biodegradle in nature
Why is the periodical table used?
So you can classify the elements into groups.
Why is magnesium a metal?
magnesium is not a metal but a reactive metal. scientists have divided all elements into two types of category: metals and non-metals to classify them as they have different chemical and physical properties. magnesium has properties of a metal so it is a metal.
Does boron belong to the metal family?
Boron is not a metal. It is a metalloid, which means it has properties of both metals and nonmetals.
A special property of pyrrhotite is that it is a natural what that attracts iron?
Pyrrhotite is a magnetic mineral that naturally attracts iron due to its magnetic properties. This makes it useful in applications where magnetic properties are desirable, such as in compasses or magnetic storage devices.
Why is internet so useful?
it makes easy to those who are lazy to scan their bokes
