What is Density of Aluminum?

Density of Aluminum

Aluminum is one of the elements of the periodic table. Also, it is a silvery-white metal that is overall a metal but does not have all properties. Besides, in this topic, you will study the aluminum and density of aluminum and various other topics that relate to it.

Definition of Aluminum

It is a chemical substance that has an atomic number 13. Also, its symbol is Al and is found in nature in raw form. Moreover, it is silvery-white texture, the non-magnetic, soft, ductile metal of the boron group.

Furthermore, 8 % of the Earth’s crust consists of aluminum and it’s the third most ample element after oxygen and silicon and is the most abundant metal in the crust of the earth.

Besides, the major ore of aluminum is bauxite. In addition, it is highly reactive and we can find it combined with over 270 different minerals. Moreover, it can resist corrosion through the phenomenon of passivation and for its low density.

Furthermore, the alloy of aluminum is very important to the aerospace industry and is important in the building and transportation industry. Moreover, the oxides and sulfates are the most common, and useful compounds of aluminum.

What is Density?

Density refers to the measure of the relationship between the space occupied by an object (volume) and its mass. In addition, this principle was discovered by Greek Scientist Archimedes. Furthermore, for calculating density we divide the mass of the object with its volume (D = m / v).

Moreover, the standard unit that we use to measure the density is kilograms per cubic meter (\(kg/m^{3}\)). Furthermore, density helps us to predict the behaviour of a substance when it interacts with others.

For example, wood floats on water because the density of the wood is less than the density of the water. On the other hand, if you throw a stone in the water it will sink because the density of stone is more than water.

Also, the densities and specific gravities relate to each other since the former is the ratio of the density of an object to the density of water. Also, the more space an object occupies the lesser dense it will become.

Properties’ of Aluminum

It is a pure metal that is discovered in the \(19^{th}\) century. Also, we can find it in many elements like feldspar and cryolite.

Besides, mostly it exists in the form of bauxite which is its most common ore. Moreover, the atomic mass of the unit is 26.98 and it has a boiling point of \(2,470^{\circ}C\) and a melting point of \(660.3^{\circ}C\).

Uses of Aluminum

There are many uses of aluminum that includes:

• When it is combined with other metal like iron and copper then it is very strong.
• Also, it is quite malleable, ductile and light and that’s why industries use them in car engines, kitchen wares, aeroplane parts, and furniture.
• Moreover, aluminum is corrosion free which makes it the ideal choice for handling chemicals and food.
• Furthermore, it is an excellent conductor of heat and due to this, we use it in electrical equipment.
• In addition, it forms a compound aluminum oxide that industries use in their processes. Furthermore, another compound like aluminum sulfate is used for water treatment and for refining petroleum they use its compound aluminum chloride.

Density of Aluminum

The density of aluminum is about 2700 \(kg/m^{3}\) that is equal to 2.7 \(g/cm^{3}\). Also, this means that every 1.0 \(m^{3}\) of aluminum has a mass of 2700 kg. Moreover, its density is constant but is heavier than that of water.

Furthermore, aluminum allows that it has a relatively lower density than steel. Also, it has one-third of the density of iron.

Solved Example for You

Question. In which unit we commonly measure density?

A. \(kg/m^{3}\)

B. \(km/m^{3}\)

C. \(kL/m^{3}\)

D. \(m/cm^{2}|)

Answer. The correct answer is option A because the standard unit of density is \(kg/m^{3}\).
