Which of the following is stated as most malleable metal? A. Copper B. Silver C. Gold D. Iron
Hint: Malleable material are those materials from which thin sheets can be formed by hammering or rolling that material.
Complete step-by-step answer:
As we know that malleable material can only be solid because only solids can be hammered or rolled.
So, most of the malleable materials are metals because most of the solid materials are metals.
But here we are given four materials and all of them are metals. So, the point is which is most malleable.
So, most malleable metal is that which can be beaten into a longer and thinner sheet from the least weight of that material by hammering or rolling that material.
So, as we know that gold will be the most malleable metal because only a single gram of gold can be beaten into a sheet of 1 square metre and an ounce of 300 square feet.
Hence, the correct option will be C.
Note: We should understand that malleability and ductility are two different properties of materials; they are not the same. Like malleable materials are those materials from which thin sheets can be formed by hammering or rolling that material. And ductility is the ability of solid to deform under tensile strength or we can say that ductile material is those which can be stretched into a wire when pulled.
