Question

Metal which is silvery light, malleable and ductile and the boiling point is around ${2050^ \circ }C$ is:
A. Zinc
B. Iron
C. Aluminium
D. Tin

Answer 1

Hint : Metal is a group of materials with strong electrical and thermal conductivity, as well as malleability, ductility, and high light reflection. Metals make up roughly three-quarters of all known chemical elements. Aluminum, iron, calcium, sodium, potassium, and magnesium are the most prevalent minerals in the Earth's crust.

Complete Step By Step Answer:
Zinc- At most temperatures, the metal is hard and brittle, but between $100$ and $150{\text{ }}^\circ C$ , it becomes pliable. The metal becomes brittle again above $210{\text{ }}^\circ C$ and can be crushed by beating. Zinc is a good electrical conductor. Zinc has low melting $\left( {419.5{\text{ }}^\circ C} \right)$ and boiling temperatures $\left( {907{\text{ }}^\circ C} \right)$ for a metal.
Iron- Iron has a boiling point of ${2861^ \circ }C$ . Steel is simply iron that has been processed to control the amount of carbon in it. At around $1750{\text{ }}^\circ {\text{ }}F$ , iron melts from the surface $\left( {{{1510}^ \circ }C} \right)$ . At ${1370^ \circ }C$ , steel begins to corrode.
Aluminium- Aluminum has a specific weight of 2.7 g/cm3, which is about a third of that of steel. Aluminum is ductile, has a low melting point, and is light in weight. It is silvery light, malleable and ductile and the boiling point is around ${2050^ \circ }C$ .
Tin- Tin is a silvery-white metal that is soft, malleable, ductile, and highly crystalline. When a tin bar is bent, the twinning of the crystals produces a crackling sound known as the "tin cry." Tin melts at at $232{\text{ }}^\circ C{\text{ }}\left( {450{\text{ }}^\circ F} \right)$ , the lowest temperature in group 14. For $11{\text{ }}nm$ particles, the melting point is reduced to $177.3{\text{ }}^\circ C{\text{ }}\left( {351.1{\text{ }}^\circ F} \right)$ .
Hence, the correct option for the given question is: (C) Aluminium.

Note :
Metal is $100\%$ recyclable, and recycled aluminium has the same properties as new aluminium. As a result, it's a far more cost-effective source material for short-run production. Aluminum remelting uses very little energy: just approximately $5\%$ of the energy used to create the raw metal is used in the recycling process.
