Question

Solder is an alloy made up of:
A.Tin and lead
B.Zinc and iron
C.Tin and boron
D.None of these

Answer 1

Hint: First we should be aware of the term alloy as the given material is of the nature of an alloy (properly mentioned in the problem statement). Now when we get to that we have to mention what is solder and what exactly is made up of which in this case are the metals of tin and lead in an appropriate amount.

Complete Step by step answer: Here in the given question statement the question is regarding the components that are involved in the formation of the alloy of solder. Now here we must get familiar with what are alloys and their basic ideology. And then we can give the explanation regarding the given alloy and the nature and other things related to it.
Now let's get to the matter of alloy. An alloy is a materialistic and well defined combination of metals. In this many metals are combined with one or more other elements. If we talk about the example we have, the combining of the metallic elements like gold and copper produces red gold. This is well used in the commercial aspect. Whereas gold and silver becomes white gold.
Now we have to come to the topic of solder,
We can say that solder is a fusible metal alloy. It is an alloy which is used to create a permanent bond between various kinds of metal workpieces. It is predominantly made up of \[60\% \] tin and \[40\% \] lead. There are various other types of solder but the \[60/40\] is the most commonly used type of solder for hand soldering.

So that provides us the correct option as option A,Tin and lead.

Note: Soldering is a process in which two or more items are joined together by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal. Unlike welding, soldering does not involve melting the work pieces.
