Have you ever wondered if Why are some things so small but so heavy? While some things look much bigger But lightweight What makes them different is one of the properties of a substance called "Density"

Have you ever wondered if Why are some things so small but so heavy? While some things look much bigger But lightweight What makes them different is one of the properties of a substance called "Density" What is density? Density is a unique property of each substance or substance. There is a relationship between the mass and the volume of that substance. Or it could be said that Density is The ratio between mass and volume. If the matter has the same volume Denser matter has a greater mass. This density is also one of the factors that cause the object to float or sink. Objects with less density tend to float on objects with a higher density.

This density is also one of the factors that cause the object to float or sink. Objects with less density tend to float on objects with a higher density. Example of a piece of wood floating in water It's because it's less dense than water. As the anchor sank It's because metal is denser than water. Balloons can soar through the air because they contain helium, which is less dense than air. Or the oil floats on the surface of the water because oil is less dense than water.

Density calculation

The density is calculated from the formula D = M / V.

Where D is the density in grams per cubic centimeter (g / cm ^ 3) or kilograms per cubic meter (kg / m ^ 3).

M is the mass in grams (g) or kilograms (kg).

V is the volume in cubic centimeters (cm ^ 3), cubic meters (m ^ 3), milliliters (ml), or liters (l).

In general, solids can be denser than liquids and gases. But this was not always the case. Because density is a specific property of a substance. Derived from atomic masses Atomic mass For example, ice has a density of approximately 0.92 g / cm ^ 3 while water has a density of approximately 1 g / cm ^ 3 due to the molecular arrangement. So if ice is placed in the water, we find that the ice floats just like icebergs or ice sheets floating in the polar oceans. Or silver, which is a solid It has a density of 10.50 g / cm ^ 3 parts mercury, which is a liquid. Back is more dense Where Mercury has a density of 13.60 g / cm ^ 3.

The densest element in the world

The densest element on the planet is osmium (Osmium, Os), a metal element on the periodic table of the transition metal group. It has a density of 22.59 g / cm ^ 3 with an atomic number of 76 and an atomic weight of 190.2 amu. It is grayish-white or bluish-white in appearance, glossy, hard but brittle. Osmium powder when exposed to air It reacts slowly with oxygen in the air and forms osmium tetroxide (osmium tetroxide, OsO4), which has a foul and toxic odor.
