Why are water molecules in the vapor phase invisible?
Water molecules in the vapor phase are invisible because they are in a gaseous state where the molecules are spread out and not densely packed together. This makes them too small and scattered to reflect or absorb visible light, which is why we cannot see them.
Why can't you use visible light to see molecules?
Visible light cannot be used to see molecules because the wavelength of visible light is much larger than the size of molecules. This means that visible light cannot resolve the small details of molecules, making them invisible to the human eye.
Which of these properties of water cannot be attributed to hydrogen bonding between water molecules?
The high boiling point of water cannot be attributed to hydrogen bonding between water molecules. Instead, it is due to the strong intermolecular forces present in water that require a significant amount of energy to overcome and transition to the gas phase.
Why do lipids float in water?
Lipids are hydrophobic molecules, meaning they do not mix well with water. Due to their nonpolar nature, lipids cannot form hydrogen bonds with water molecules, causing them to aggregate together and float on the surface of water. This is because the hydrophobic interactions between lipid molecules are more favorable than the unfavorable interactions with water.
Why is water particles smaller than pieces of sand?
Water molecules are smaller than grains of sand because they are composed of two hydrogen atoms and one oxygen atom, while sand particles are typically made up of multiple atoms bonded together. Additionally, the molecular structure of water allows the molecules to be more tightly packed together, resulting in a smaller size compared to sand particles.
How can molecules of water change?
They cannot and they do not change.
Why are water molecules in the vapor phase invisible?
Water molecules in the vapor phase are invisible because they are in a gaseous state where the molecules are spread out and not densely packed together. This makes them too small and scattered to reflect or absorb visible light, which is why we cannot see them.
Is it possible to see a mole of water with the naked eye?
No, it is not possible to see a mole of water (6.022 x 10^23 molecules) with the naked eye due to their extremely small size. A mole of water would consist of trillions of water molecules, far beyond what can be seen without the aid of a microscope.
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.
Why can't you use visible light to see molecules?
Visible light cannot be used to see molecules because the wavelength of visible light is much larger than the size of molecules. This means that visible light cannot resolve the small details of molecules, making them invisible to the human eye.
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 can you see into water but when in water you cannot see out?
Because water is duty and because the sun
Why oil cannot be mixed with water?
because oil is a heavier liquid and water is a lighter liquid. you can see this by pouring some water and oil in a glass cup and wait until it settles. you can see that oil will be on the bottom and water will be on top.
Why we cannot see the salt particle when it is added to the water?
We cannot see the salt particle when it is added to the water because it dissolves
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
