Molecules are often visible if you have enough of them. Enough carbon molecules and you have coal.
Bleach removes dye by breaking down the color molecules in the dye, making them unable to reflect light and thus appear invisible. The bleach's chemicals cause a chemical reaction with the dye molecules, altering their structure and causing them to lose their color.
As you probably learned in high school, the atoms inside solids and liquids are much closer than those inside gases. The gaseous atoms are so far apart that it is beyond the abilities of our eyesight to see it, as we must rely on our smell and nerves to tell anything like that.
The molecules in a solid are held together by short invisible bonds. A way to think about these bonds is that they slowly stretch as they move towards gas form. So in a solid the bonds are stronger and shorter, without them being held in such close proximity to each other they wouldn't be able to hold there shape, resulting in a more liquid form. Now in short, it is so the invisible bonds can more easily control the molecules in the object.
LIQUID-spread apart and moving but not too much. GAS-spread around and moving at a rapid pace. SOLID-Compact and stuck to eachother. Think of it like this. When you add heat to water you know it turns into gas. Whats happening is that the molecules are getting crazy and moving all around. ~answered by a student studing for a test. :)
Yes, baking soda can be mixed with water to create invisible ink. When the solution dries on paper, the writing becomes invisible and can later be revealed by applying heat or a second solution (such as vinegar).
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.
Correction: Invisible Yes. Water Vapor is invisible unless they gather in one place, then they become Water molecules.
Most gases are invisible to the naked eye. Gases are made up of molecules that are spread out and don't absorb or reflect light in a way that makes them visible. However, some gases do have odors that can be detected.
Wind is invisible because it is made up of moving air molecules that are transparent to the human eye. We can only see things that reflect or produce light, and air molecules do neither. Wind becomes visible when it carries objects like dust, leaves, or water droplets.
It depends on the amount of water boiled to make that vapor.
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.
Gas is typically invisible because its molecules are spread out and move freely, allowing light to pass through without significant distortion or absorption. This is why we cannot see gases like air or oxygen with the naked eye.
It depends what you mean by simplest. If you mean the smallest forms of matter, they are microscopic not invisible. If you mean basic components of matter such as quarks, atoms, molecules and so on, the answer is again that they are subatomic to microscopic in size and so not able to be seen without aid, yet not invisible. The only things that are truly invisible neither absorb nor scatter light, and therefore we can not see them in the visible light spectrum, like dark matter.

A smell is indeed matter, it is small invisible chemicals dissolved in the air that your nose is able to detect when these molecules land on them as you breath (sniff) the air.
Viscosity refers to a fluid's resistance to flow, which is influenced by the internal friction between its molecules. Surface tension is the result of cohesive forces between molecules at the surface of a fluid, causing it to behave as if it were covered by an invisible membrane.
