Liquids More Dense Than Water or Alcohol (2024)

FAQs

Which liquid is more dense water or alcohol? ›

Which liquid is more dense water or Alcohol? A: Well, I cannot speak for all kinds of alcohols, but the common ones (methanol, ethanol, and isopropyl alcohol) are a little less dense than water. All three of these have densities of about 0.79 g/cc at standard temperature and pressure, compared to 1.0 g/cc for water.

Alcohol is less dense than water so spirits can float on top of water or juices. They don't mix because, unless they are stirred up, natural mixing of fluids is actually a very slow process.

The density of a liquid is a measure of how heavy it is for the amount measured. If you weigh equal amounts or volumes of two different liquids, the liquid that weighs more is more dense.

Oil is more dense than alcohol, but less dense than water. The molecules that make up the oil are larger than those that that make up water, so they cannot pack as tightly together as the water molecules can.

Methanol, dimethyl ketone, methyl ethyl ketone, propanol, isopropyl alcohol, and several others would have a lower viscosity, IE be “thinner” than water.

Mercury is the heaviest liquid at room temperature. But the heaviest liquid irrespective of temperature is liquid osmium (a rare metal) at its melting point (3033°C/5491.4°F), with a density of 22.59 g·cm⁻³, 1.65 times as heavy as mercury.

In ethanol hydrogen bonds are not as strong as water . Its molecules can pack closely together,so space between water molecules is less than the space between alcohol molecules. which means that it has more mass in the same volume than ethanol. So, water is more dense than ethanol .

Introduction: Liquid density depends on the amount of solute dissolved in the solution. If there is a higher concentration of solute, such as NaCl, then that solute has a greater mass in that solution. In the same volume of water that solute will have a greater mass in turn causing it to have a higher density.

Saltwater is more dense than isopropyl alcohol, so the alcohol floats on top of the saltwater.

Lighter liquids (like water or vegetable oil) are less dense than heavier liquids (like honey or corn syrup) so they float on top of the heavier liquids. The same amount of two different liquids you used in the container will have different densities because they have different masses.

Can humans float in ethanol? ›

You cannot float in 80-proof [40 per cent] alcohol – even with lungs fully inflated, your body is denser than the liquor and you will sink if you stop swimming. 2) The fumes will probably cause you to choke and cough.

Answer and Explanation:

Since the density of the vinegar is d v ≈ 1.01 g / m L at 25 ∘ C . Thus, The density of the vinegar is a little bit greater than the density of the water. Hence, we can say that the vinegar will sink if it is added to water.

For liquids that exist at room temperature and pressure, isopentane at 0.616 g/mL is a good possibility. If you want to be more exotic, liquid hydrogen (0.0708 g/mL) and liquid helium-3 (0.059 g/mL at its boiling point) are good candidates.

Correct answer:

The most dense liquid will sink to the bottom, and the least dense liquid will rise to the top. We know that the milk was underneath the water in the beaker, so we can conclude that milk has a greater density than water.

Water has a density of 1.00 gram/mL therefore those objects with a density of less than 1.00 gram/mL will float in water. 70% isopropyl alcohol has a density of about 0.88 g/mL therefore those pellets with a density of less than 0.88 g/mL will float in alcohol.

The refractive index of alcohol is more than water, therefore, alcohol is optically denser medium.

ALCOHOL SIMPLY DOESN'T FLOAT ON WATER. IF IT'S 70% ALCOHOL IT MEANS IT'S 30% WATER.
