Oxygen is necessary for combustion to take place. When a candle burns, it reacts with oxygen in the air to produce a flame. Increasing the oxygen supply will result in a hotter and more efficient burn, causing the candle to burn more quickly. Conversely, reducing the oxygen supply will cause the flame to burn more slowly or even extinguish.

Why does a candle burn for a long time in a jar with no lid on?

When a candle burns in a jar with no lid, it has a limited oxygen supply due to the confined space. This causes the candle to burn more slowly and last longer as it consumes less fuel at a time. The heat generated by the flame also creates a convection current that draws fresh air into the jar, sustaining the flame.


Does the brand of the candle determine how fast it burns?

Because if you were making the candle, how long it burns would be determined on what size the candle is, what shape the candle is, what size wick and how many wicks you put in it and what kind of Wax you used. ie: Parrafin, Beeswax or Soy etc. And different companies are going to use different materials.


What makes a candle burn so long?

What burns faster a short fat candle or thin long candle and why?

A long candle because the flame won't melt on the edge so it wont burn that, and the wax in the middle gets too deep and the fire goes out due to lack of oxygen. A long and thin one uses all the wax and since it so thin it burns faster.
