Gas can sometimes be visible with the example of smoke from a cigarette but it is also invisible as in the case of carbon monoxide which could not be seen or smelled.
What i can say is that it is invisible
Plasma. It makes up more than 99% of visible matter in the universe, and most of the invisible matter.
It is called dark matter. Dark matter is undetectable and invisible.
It is invisible.
Ice is a state of matter when referring to water. In a way ice is indeed "invincible" since matter can not be created or destroyer. So really there is no way to "destroy" ice.
Although many people think they are in solid form or water vapor, clouds are actually liquid water. It's impossible for them to be water vapor, because vapor is invisible. Clouds are not invisible.
Dark matter is invisible. It doesn't interact with light.
matter must have mass and volume.though it may be visible or invisible.
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.
That matter was made of invisible particles
