Most gases are invisible, however there are some that when housed in high enough concentrations in transparen't containers have very bright colors.
The problem is that to "see" a gas you will really have to look at the atomic level. That is because gases are comprised of individuals atoms or molecules flying around in every direction, somewhat willy nilly. If they arent contained then they will all fly away and get "lost" then you will then just have a mix of gases like our atmosphere.
Even with water vapor, by the time you "see it" it is really already condensed and is technically a liquid again.

It simply means that the substance is in a "gas" form, like oxygen, nitrogen, water vapor, etc. Its appearance will vary widely from substance to substance. Some gasses are visible, others are not.
More info on wikipedia: "A gas is one of the four major phases of matter (after solid and liquid, and followed by plasma, that subsequently appear as a solid material is subjected to increasingly higher temperatures. Thus, as energy in the form of heat is added, a solid (e.g. ice) will first melt to become a liquid (e.g. water), which will then boil or evaporate to become a gas (e.g. water vapor). In some circumstances, a solid (e.g. "dry ice") can directly turn into a gas: this is called sublimation. If the gas is further heated, its atoms or molecules can become (wholly or partially) ionized, turning the gas into a plasma."

Looks like vapor swirls. Sometimes you can see the vapors as the gas starts to cool down. An example would be water. When it is in the gaseous state you can see steam. In the case of frozen water (ice) when you blow across the ice cubes, you can see "frost".

It sounds like it quite is touching on the entire entropy of the universe. There could be good gadgets which contain meteorites that would desire to be burning up in to gas theoretically on the comparable time balancing out the entropy. it rather is in easy terms a wager although. study Stephen Hawking's a short historic previous of Time, it talks approximately this way of stuff.

It would be different for different chemicals.
In general, the difference between the 2 fluid states, liqid and gas, is that gas will generally expand to fill its container. While liquid conforms to its container shape, it has a relatively fixed volume.

Steam from boiling water is classic example,

well i think it might depend on maybe like the type of gas does it have a color?? but if it doesnt then you prolly dont actually see it
