Why Does Ice Float? [Now You Know!]

One of those many questions that people have, whether they need to know or out of sheer curiosity, is whether all liquids weigh the same

And if not, which liquids weigh the most and which are the lightest?

Contrary to what you might think, not all liquids weigh the same in terms of pounds and ounces

Like solids, liquids have different densities and components that determine how heavy they are

However, while they may be similar, most liquids of the same volume do not weigh the same amount

Various liquids such as water, oil, milk, liquor, and so many more have different densities

How Much Does Water Weigh? Here is a table showing how much different quantities of water weigh

Because water is the most common of all liquids, it is often what other liquids are compared to in terms of weight and density

In terms of density, which is what determines how heavy a liquid is, mercury is the heaviest liquid in the world

Mercury is 136 times denser than water, which means it weighs quite a bit more per gallon

However, mercury in its liquid form is extremely deadly, so you should definitely not try to weigh the two liquids yourself

Steel, iron and lead are heavier than water when melted into a liquid

For example, water is more than ten times denser than hydrogen in its liquid form and is, therefore, more than ten times heavier

Liquid propane, which is what millions of people around the world rely on for their energy, weighs about half that of water

However, in terms of liquids we use or see every day, alcohol and oil are two of the lightest in the world

Alcohols such as ethanol, methanol, and isopropyl weigh about 79 grams per cubic meter, while water weighs 1 gram per cubic meter

If you have ever mixed oil and water, you have probably noticed that the oil floats on top of the water and does not mix with it

This is because oil is slightly lighter than water

As we just learned, alcohol is slightly lighter than water, which seems to indicate that wine weighs less than water

However, on average, wine is only about 10% alcohol, and the rest is made up of sugar and other additives

Basically, it all depends on what type of wine you are pairing with water

Wine that is high in alcohol content and low in sugar will weigh less than water

However, certain commercial wines with high sugar content and low to medium alcohol content will only weigh the same amount as water or more

Does Alcohol Sink Or Float? If you ever try to mix pure alcohol such as ethanol, methanol, or isopropyl with water, you will have a hard time

Pure alcohol is lighter than water, which means it will float on top rather than mixing or sinking to the bottom

Is Water Heavier Than Coffee? Whether or not water is heavier than coffee depends on the type and texture of the coffee

Whole coffee is expected to sink in water which means it is denser

However, liquid coffee is different in weight and density from whole coffee

Do Milk And Water Weigh The Same? Milk and water are two of the most similar liquids there are in terms of weight and texture

However, milk actually weighs slightly more than water when you compare a gallon of milk to a gallon of water

Milk is only 87% water and the rest is made up of components that are heavier than water, apart from fat

Fat is lighter than water, so, in theory, if milk has a high enough fat content, it can be as light as water

However, there is rarely if ever enough fat in milk to make it equal in weight to water

In terms of household liquids and what they weigh, the pyramid looks like this from heaviest to lightest: syrup, milk, water, oil, and alcohol
