How does the rearrangement of water molecules as they change state affect the density of matter?

The most dense arrangement is actually the liquid water. Here, the molecules are close together, so the liquid is dense. As the water changes to gas, the molecules gain enough energy to break the gravitational fields formed at a close distance and speed away from each other, so the same molar weight would be spread over a larger area, lowering the overall density. In ice, the hydrogen bonds can slide over each other. I'm not too sure about this or how it makes ice less dense, so look this up elsewhere, please :) Anyway, you just need to know that water is the most dense, next dense is ice and least dense is gas.

Is density a physical or chemical change or is it a physical and chemical change?
Your answer will be physical property.It can also be physical change when you're telling the density of an object. And the reason why is "density" is... physical is just those kind of stuff...
Does the volume of water change the density of water?
Density = mass / volume. So if the volume changes, the density will obviously also change.
Do lipids cause molecules to change?
No, lipids are not capable of causing molecules to change. The items that actually cause them to change are enzymes.
How does change in phase affect entropy changes in a reaction?
It happens because, even in the same compound, atoms/molecules in different phases have different types of behaviour. For example, unlike solids, liquid and gas molecules can 'flow' around.
Why does the density of a substance not change no matter how much of the substance you have?
Because density is a "ratio".
How does the rearrangement of water molecules change state of matter?
There are empty spaces between the particles of matter that are very large and that can be used to identify a substance because they never change.
When gaseous molecules are compressed they tend to?
They tend to change density, temperature or energy.
Does a change in the mass affect the density of the object?
Adding mass may increase or decrease the density if the substance added is different. Merely changing the mass will not affect the density.
Does water weigh more as a solid a liquid or a gas?
If you are talking about the exact same quantity of molecules, these changes don't affect the weight. Things like density and buoyancy may change, but not the weight.
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.
How does the pitch change the density of an object it travels through?
It makes the molecules vibrate so the density chages. Your question is a bit unclear.
Is temperature the only thing that affects density?
It is the easiest way to affect the volume which would change the density. However, if you increase the pressure but keep temperature constant the volume will also change. Any change in volume affects density.
How do molecules change the air pressure as you move away from the earths surface?
their density decreases as you go up

Do isomers of the same molecule have identical chemical properties?
When two molecules have different configurations but the same atomic composition the two molecules cannot be said to have the same physio-chemical properties. In fact, a simple rearrangement, even with identical chemical formulas, can drastically change the properties of a substance.
Why density does not change with volume?
Density is how tightly packed the matter in a substance is. Therefore, how much space it takes up (volume) will not affect this.
When mass changes does it affect the density of an object?
yes it does it can change for many reasons ~destiny
