Elemental magnesium is a gray-white lightweight metal, two-thirds the density of aluminium. Magnesium has the lowest melting (923 K (650 °C)) and the lowest boiling point (1,363 K (1,090 °C)) of all the alkaline earth metals.
21 lis 2020 · Density of Magnesium is 1.738g/cm3. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume. It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V.
Magnesium is one-third less dense than aluminium. It improves the mechanical, fabrication and welding characteristics of aluminium when used as an alloying agent. These alloys are useful in aeroplane and car construction.
Magnesium weighs 1.738 gram per cubic centimeter or 1 738 kilogram per cubic meter, i.e. density of magnesium is equal to 1 738 kg/m³; at 20°C (68°F or 293.15K) at standard atmospheric pressure.
Density of Magnesium is 1.738g/cm3. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume. It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V.
Magnesium is the eighth most abundant element in the earth's crust. It does not occur uncombined, but is found in large deposits in the form of magnesite, dolomite, and other minerals. Los Alamos National Laboratory, U.S. Department of Energy.
Magnesium is a very light metal. Only calcium and the alkali metals are lighter. This low density is used to advantage in alloys like magnalium (10% magnesium, 90% aluminum). Magnesium reacts with boiling water to form magnesium hydroxide and hydrogen gas.
