Densidad: Alcohol Etílico

This phenomenon, known as volume contraction , means the density of the mixture is not an average—it is higher than expected. This is the secret weapon of the beverage industry. A 40% ABV (Alcohol by Volume) whiskey isn’t just water + alcohol; it is a unique physical hybrid. Distillers use precise density tables to pay their taxes, because the government doesn't tax the volume of liquid you have—it taxes the actual mass of alcohol inside. If you think mixing is tricky, try heating it up.

At first glance, the number seems trivial. The density of pure (anhydrous) ethyl alcohol at room temperature (20°C / 68°F) is approximately . But don't let the "0.789" fool you. This tiny decimal point is a chemical rebel, and its behavior tells a fascinating story. The Rebel Who Floats Let’s start with the most obvious magic trick: density is why your "heavy" rocks sink and your "light" cork floats. Water has a density of 1.00 g/cm³. Ethanol, at 0.789, is significantly lighter. alcohol etílico densidad

When you hear "ethyl alcohol" (or ethanol), your mind probably jumps to one of two places: a stiff glass of whiskey or the sterile sting of hand sanitizer. But hidden within this simple molecule—C₂H₅OH—lies a physical property that dictates everything from the price of your vodka to the safety of space travel: density. This phenomenon, known as volume contraction , means
