you may not see it but once you blow out the candle, small embers are still inside the wick of the candle and burning. because the embers are so small thriving off the air particles thus creating the smoke you see.Additional answerIt does smoke while burning, if you look closely enough. In fact, if you put a piece of glass or tin above the flame it will become blackened with smoke particles (carbon).
Air is composed of transparent gases like nitrogen, oxygen, and carbon dioxide, which do not scatter visible light enough for us to see them. This lack of interaction with visible light makes air appear invisible to the human eye.
Water evaporates at a molecular level, so it is not visible to the naked eye. The process of evaporation occurs as water molecules gain enough energy to break free from the surface and turn into water vapor, which is invisible.
When a candle burns, a chemical change known as combustion occurs. The heat from the flame is used to vaporize the wax, which then reacts with oxygen in the air to produce carbon dioxide and water vapor. This chemical reaction releases heat and light, which is what we see as the flame.
Fire is not invisible; fire is the chemical chain reaction from combustion that creates heat and light. Combustion, which is the actual burning process, is strictly chemical rearrangement and is invisible - but once you add oxygen to it, it becomes visible as fire.
Air is invisible to see.
The writing on the wall? Air?
Purple is the color the flame gets when it is very, very hot. I don't know how a candle can get that hot, though. It's got no spiritual meaning! It's just hot!
What Faraday basically said was that when you burn a candle, you see the formation of a "beautiful cup". This cup is formed as the air near the candle moves upward due to heat of the candle.
They used there freshly squeezed urine. Then let it dry. Then held it over a candle to see it.
Hot air is lighter. See the related link.
One can see an invisible laser beam by using special equipment like a laser beam detector or by observing the beam's reflection off of particles in the air.
If the files are invisible I do not think that you can see them.
The properties of air is that it is odorless and colorless. There are many gasses and liquids that have these properites, such as Oxygen and Nitrogen and Carbon Dioxide. Air is a mixture of these gasses.
To See the Invisible Man was created in 1963.
You can see your house from the air. You could be in an airplane or a hot air balloon.
See if hot wire hot with switch on.
