No, everything burns faster in oxygen than in air. Very little can burn without any. In air, close stove vents to slow it or use belows to blow on it to increase the rate of burn. Pure oxygen from a gas bottle can cause dangerous rapid oxydation, dangerous flare ups and flash fires. That's why welders store the green gas bottles outside and so far from the fuel bottles.
In a large jar as there should be more oxygen.
Yes, thicker candles have more wax to burn and therefor take longer to burn out.
The burning flame on a candle needs three things to continue burning: 1) fuel, which it gets from the wick 2) heat, which comes from lighting the candle 3) oxygen Without any one or more of these three things, the candle will no longer continue to burn. In the case where a candle is covered with a glass, the candle quickly uses up the oxygen inside the glass. once all of the oxygen is gone, the flame will burn out.
a flame needs oxygen to burn so if you put a lit candle in a closed container (like a jar) the oxygen will continue to fuel the fire until there is no more oxygen and the candle will go out
Usually oxygen, primarily because it is how fire is made. But for longer, there isn't a possible way to make it burn 'longer' with gas, but more rather use wax and string that are more durable to fire. Or alternatively you can put a plant near the fire (out of burning range) to give the fire as much oxygen as possible. hope it helps
Candle burns oxygen. Plant produces oxygen from Carbon Dioxide. plant produces oxygen, which is burned by candle. Candle lasts longer because more oxygen is present
Air contains about 21% oxygen, so the candle in air might only burn 21% as long as a candle in oxygen. Of course, that does not include other variables, like the candle burning in oxygen will burn hotter, melting the candle wax sooner.

yes.you need more air,as the candle will burn for longer in a bigger volume of air because the air contains oxygen which is needed for combustion
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.

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.The burning of the candle (a chemical reaction) is affected by the number of oxygen molecules around it.So the speed of the chemical reaction is affected by the concentration of oxygen

The Smaller the jar the less oxygen, the bigger the jar the more oxygen, and since the candle lives of oxygen the biggest jar with the candle in it will take the longest to burn.

colour is colour... it depends on the make, if its a more expensive candle, it will last longer if the brand is quality
