After oxygen and silicon, it's the third most common chemical element on the earth.Īluminum is a silvery-white metal that is overall a metal but does not have all properties. One surprising fact about aluminum is that it is the most common metal on the planet, contributing to more than 8% of the planet's core mass. Further resources are available for learning more about aluminum and its properties.Aluminum is the 13th element in the periodic table, and it is a silvery-white metal. Understanding the density of aluminum is essential for those working with this metal in any capacity. Finally, the density of aluminum can be calculated by measuring the mass and volume of the sample and then dividing the mass by the volume. Temperature and pressure can both affect the density of aluminum, as can the alloy composition. Aluminum has a lower density than many other metals, such as steel and copper. In conclusion, the density of aluminum is an important concept to understand when considering the use of this metal in industry and everyday life. The density of aluminum can vary depending on the alloy composition and other factors. Copper has a higher density than aluminum at 8.96 g/cm3. For example, steel has a density of 7.85 g/cm3 while aluminum has a density of 2.7 g/cm3. Comparing the Density of Aluminum to Other Metals Comparing the Density of Aluminum to Other MetalsĪluminum has a lower density than many other metals. These properties make it an ideal material for many applications. It is also highly reflective and has good electrical and thermal conductivity. It is the most abundant metal after iron and has the atomic number 13.Īluminum has several unique properties, including high ductility and malleability. Aluminum is abundant in the Earth’s crust, making up 8.3% of the total mass. It was later isolated in 1827 by German chemist Friedrich Wöhler. The History and Science Behind the Density of Aluminum The History and Science Behind the Density of AluminumĪluminum was discovered in 1825 by Danish chemist Hans Christian Oersted. This makes aluminum a sustainable and environmentally friendly option. It is also highly recyclable and can be reused multiple times without losing its properties. Aluminum has excellent corrosion resistance and is non-toxic, making it safe for food and beverage containers.Īluminum is a great choice for many applications due to its low cost, strength, and light weight. It is also used in electronics and appliances. Common uses include construction, packaging, and transportation. It is lightweight yet strong and durable, making it ideal for many uses. Examining the Role of Aluminum in Everyday Life Examining the Role of Aluminum in Everyday LifeĪluminum plays an important role in everyday life. Once the mass and volume are known, the density can be calculated by dividing the mass by the volume. This can be done by filling a graduated cylinder or other volumetric container with the sample and measuring the amount of liquid displaced. Next, the volume of the sample must be determined. First, the mass of the sample must be measured using a scale or balance. How to Calculate the Density of AluminumĬalculating the density of aluminum is fairly simple. Different alloys can contain different amounts of other elements such as copper, zinc, and magnesium which can either increase or decrease the density of the aluminum. The alloy composition of the aluminum can also affect its density. Conversely, increasing pressure causes the density of aluminum to increase. As temperature increases, the density of aluminum decreases. Temperature and pressure can both have an effect on the density of aluminum. What Factors Affect the Density of Aluminum? Another method involves measuring the volume of the aluminum sample using a graduated cylinder or other volumetric container such as a beaker. The mass of the sample is weighed and then divided by its volume to calculate the density. One way to measure its density is by using a scale or balance. The density of aluminum can be measured using a variety of tools and methods. The SI (International System of Units) unit for density is kilograms per cubic meter (kg/m3). In other words, it measures how much matter is contained within a certain space. Simply put, density is the amount of mass per unit volume of a substance. To understand the density of aluminum, it is first important to define what density is. Explaining the Density of Aluminum in Layman’s Terms This article will explore what the density of aluminum is and how it can be measured, calculated and compared with other metals. It is a measure of the mass of a given substance, in this case aluminum, relative to its volume. The density of aluminum is an important concept to understand when considering the use of this metal in industry and everyday life.
