It's about wavelength and size. The wavelength you use to look at an object has to be shorter than the object. And visible light has a wavelength that is longer than a molecule.

Which of these properties of water cannot be attributed to hydrogen bonding between water molecules?
non polar molecule
Why cant we see the molecules of water moving around?
Individual molecules are too small.
Why water expands on solidification?
due to hydrogen bonding bettween water molecules.
How do ice water molecules differ from warm water molecules?
The main difference is that ice water molecules have very low kinetic energy, i.e. they don't move very fast, compared to warm water molecules. The other difference is in the intermolecular forces holding the molecules together. They are greater in ice than in warm water.
Why is water particles smaller than pieces of sand?
Because You Cannot See All The Particles In Water.. In Sand You Can See Them. Example: You CAN See A Grain Of Sand. SOURCES: Brain, School, Life,
How can molecules of water change?
They cannot and they do not change.
Why can you not see salt when it is dissolved in water?
because the salt molecules have mixed up with the water molecules
What do molecules do in water?
Hydrophobic molecules do not dissolve in water. This is because water is hydrophilic. Another way to say this is that lipids, which are nonpolar, cannot dissolve in water, which in polar.

non polar molecule
Sentences with molecules?
Two sentences using the word molecules would be: The smallest units of water are called molecules. Molecules cannot be seen by the naked eye.
Why cant we see the molecules of water moving around?
Individual molecules are too small.
What polar molecules are attracted to water?
Hydrophobic molecules do not dissolve in water. This is because water is hydrophilic. Another way to say this is that lipids, which are nonpolar, cannot dissolve in water, which in polar.
When a solid dissolves in a liquid it seems to disappear into it. how is it possible?
The solid separates down to the molecular level - and they mix with the water molecules. We cannot see molecules with the naked eye !
Why can oxygen water and carbon dioxide move through the cell membrane but salt and protein cannot?
That depend on size and the charge.Large molecules and charged molecules cannot move freely
What property of water is demonstrated when you see beads of water on a waxed car hood?
surface tension, caused by the high attraction of water molecules for other water molecules.
Why can you see into water but when in water you cannot see out?
Because water is duty and because the sun
What is the state of mater of water vapor?
Water vapour is not a gas. We can not see gas. Once we see the water vapour as droplets in the air then it is small liquid droplets of water. The steam that we see above the kettle is again condensed droplets of water that have lost the energy to maintain their gaseous existence. Close to the spout of the kettle we cannot see steam because that is where there is the gas molecules of water. If you can see it then it is a liquid. Humidity in the air is a gas.
