What liquid is lighter than water?
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….How Does It Work.
| Material | Density (g/cm3) |
|---|---|
| Water | 1.00 |
| Ice Cube | 0.92 |
| Vegetable Oil | 0.92 |
| Baby Oil | 0.83 |
Is isopropyl alcohol lighter than water?
The liquids must have different densities because the ice cube floats in one but sinks in the other. Explain that since ice floats in water, liquid water must be more dense than ice. This means that water and isopropyl alcohol must have different densities and that the water is more dense than isopropyl alcohol.
Is vinegar heavier than water?
Water has a density of about one gram per cubic centimeter (depending a little on temperature and pressure). Household vinegar consists almost entirely of water, but with some acetic acid molecules dissolved in it. In general, dissolving stuff in water makes it more dense, making vinegar the densest of the three.
Is Honey heavier than water?
