What type of molecules float in water?
Nonpolar molecules that have a lower density than that of water (<1g/mL) will float above water.
Is it always true that the molecules of dense liquid are heavier than the molecules of lighter molecules?
NO. Water has a density greater than gasoline, but gasoline, octane anyway, has a greater molecular mass than water molecules.
Does the pressure of a liquid depend on its density?
Density is an intrinsic property, and as such it does not depend on the size of the object. A drop of water will have a density of 1g/ml whether it is a big drop, or a very small drop.
Why is density of water more in deep water?
The density of water increases with depth due to the increase in pressure. As water molecules are packed closer together under high pressure, the density of water increases. Therefore, in deep water where the pressure is higher, the density of water is also higher.
What are examples of practical applications for density?
An example of real life density is "ice floating on water." Ice floats on water because it is less dense than water. Things that are less dense float on top of things that are more dense because molecules in ice are further apart than molecules in water.
What do molecules of ice have less of than molecules of water?
The chemical formula is absolutely identical - H2O. The density of ice is lower than the density of water.
What type of molecules float in water?
Nonpolar molecules that have a lower density than that of water (<1g/mL) will float above water.
What is density from the properties of water?
density are molecules that hold together that's how things float and skee

Why liter of water is heavier than liter of ethanol?
The density of water is greater than the density of ethanol. This is partly a result of how tightly packed the molecules of the substance are.
What happens to the level of molecules as water cools?
Nothing they stay the same - their density changes.
How does the density of water change as it expands?
Since "expansion" in this case refers to the increased spacing between molecules, then the density must decrease.
Explain why the density of thick syrup is greater than the density of water?
The syrup is more dense because its molecules are closer together.
Why is density of water more in deep water?
The density of water increases with depth due to the increase in pressure. As water molecules are packed closer together under high pressure, the density of water increases. Therefore, in deep water where the pressure is higher, the density of water is also higher.
The fact that ice is less dense than water is related to the fact that?
Water forms hydrogen bonds, which lock the water molecules into crystals that have less density than the distances between water molecules in a liquid state. Without these hydrogen bonds, such a difference in density would not be present.
Why is friction greater in water?
A gas like air, is marked by lower density of molecules than a solid or liquid. Friction is caused by molecules bumping into eachother, so the more molecules there are to run into, the higher the friction. So, air has less molecules per cubic foot and therefore has less density and less friction than water.
