when a candle burns, the wax is reacting with oxygen in the air to give out heat and light. If you give the candle more oxygen then it will burn brighter, but it will burn out more quickly. It all depends whether the candle has a high or low concentration of oxygen. The main reason why the candle burns brighter is because there is a better chance that the oxygen will bump into the wax on the wick. when a candle burns, the wax is reacting with oxygen in the air to give out heat and light.

How fast does a candle burn?
It depends on what kind of wax that the candle is made out of
What makes a candle burn faster?
The speed of a candle burning probably depends on many things. Just by thinking around, we could guess that it depends on the width of the wick, the rate at which the liquid wax flows into the wick (which depends on the wax viscosity and the shape of the candle), and the rate at which oxygen can be supplied to the flame. This, in turn, depends on the dynamics of the airflow around the flame, which probably depends in part on the energy density of combustion of the liquid wax. I would guess that the scent added to candle wax influences the viscosity of the liquid wax and its energy density of combustion. I'm sure, with sensitive enough instruments, you could measure the effect of different scents on candle combustion. But would you ever notice this effect in everyday life? That depends on the relative proportion of scent to wax in a candle. I'm guessing that it doesn't take much scent to make a candle smell. Even though are noses aren't as good as dog noses, we can still detect tiny concentrations of scent molecules in the air. Also, most scents are volatile organic molecules, and their addition in large proportions to wax might prevent it from forming a solid. So, is there enough scent in a scented candle for you to notice its effect on the burn in everyday life? Probably not. If there are particular candles you're curious about, then you can answer this question for yourself. Do an experiment! :) Experiments are fun, and this one is also really easy. Take two candles that are identical--except for the scent-- And then put them next to each other, and light them at the same time. You could do this experiment anywhere. You don't have to worry too much about the air in the room being still, because the candles will be next to each other, and they will experience almost the same variations in airflow. So set the candles up in your living room or kitchen. You can even put them out when you go to bed, just be sure to relight them at the same time. Have fun!
How does the atmosphere keep oxygen inside?
Inside what? Oxygen is part of the atmosphere. The thermal velocity of its molecules are insufficient to escape earth's gravity (unlike hydrogen molecules which are fast enough).
How does running affect your heart rate?
Running effects the body by making the hear rate rise through rapid respiration. While running the lungs must breath in and respire air quickly causing the heart to pump more blood quickly through the body.
Why does fast dancing affect your heart rate?
Your heart rate increases because the carbon dioxide in your body is building up and your body is trying to release it, because your body uses up so much oxygen while you're exercising and turns it into carbon dioxide, it builds up much faster and your body has to work harder to release it.
Does the size of a candle affect how fast it will burn?
just do the experiment... but i think so.
Does the amount of accessible oxygen affect how fast a candle burns How Please be specific?
Yes, it does.
How fast does a candle burn?
It depends on what kind of wax that the candle is made out of
Does the container of a candle affect how fast it burns?
no
What is the reason for a yellow candle to burn faster than a colored candle'?
actually the color does not effect how fast the candle burn, i got confused of " Does candle's color effect how candle's burn?"but i think the color does not effect how candle burns. But some people will think that the white or yello candle will burn slower because color will obsorb the heat more. Hope i have answered your question.
How fast can a candle burn if it is lit?
There is no way to tell unless you know the size of the candle, the exact makeup and proportions, the environment surrounding the candle etc.
Why does a candle burn faster outside then inside?
If it is warm outside, like in spring or summer, then it will burn faster because the environmental temperature is warmer, causing the candle to melt. When a candle is burned inside, it will not burn as fast because there is no extra push in melting it.
Does the color of the candle affect how fast it burns?
Yes the colour does affect how fast it burns!The color of the candle does affect how long it burns because the heat is produced to darker colors then lighterbut it does not if its a all different colors
How does the shape of a candle affect how fast it burns?
The shape of a candle affects how fast it burns because if you have a round candle it would be shorter than a cylinder. The smaller the shape the faster it burns.
Why do candles burn at different rates?
The type of wax is going to dictate the burning rate of a candle, as will the diameter of the candle. A large diameter candle will burn its length more slowly than a small diameter one. Think how fast birthday cake candles burn down.
Does temperature affect how fast a candle will burn?
Yes. My 7 year old did this as a science experiment. He used 3 pilliar candles, left one on the counter, put one in the fridge, and one in the freezer - all for 24 hrs. He then lit them and let them burn for 3 hours, checking every 30min. At the end of the 3 hours, the one left on the counter was burned down a lot, the one in the fridg, not as far and the one from the freezer was hardly melted at all.
Why does zinc burn up fast?
It reacts with oxygen and nitrogen well.
