hobbies and interests candle and soap makingWhat happens when u burn a candle?
As the candle burns, solid wax becomes liquid and then evaporates to become a gas. The gaseous wax burns in oxygen to produce water, carbon dioxide, heat and light. The burning candle also produces carbon, in the form of the black soot we see on the spoon.
In this manner, what happens to candle wax when it burns away?
The heat of the flame vaporizes the wax molecules and they react with the oxygen in the air. As wax is consumed, capillary action draws more liquid wax along the wick. As long as the wax doesn't melt away from the flame, the flame will consume it completely and leave no ash or wax residue.
Moreover, is it safe to burn a candle in a closed room?
A candle burns carbon molecules. If you sleep with a burning candle in closed room. Room will have limited amount of oxygen. Candle will continuously consume oxygen and convert it into carbon dioxide and carbon monoxide.
For a candle to burn, a heat source (commonly a naked flame from a match or lighter) is used to light the candle's wick, which melts and vaporizes a small amount of fuel (the wax). Once vaporized, the fuel combines with oxygen in the atmosphere to ignite and form a constant flame.
