Why the candle could not burn when gas left in the jar?
When gas is left in the jar, it displaces the oxygen needed for the candle to burn. Oxygen is required for combustion to occur. Without enough oxygen present, the candle will not be able to sustain the flame and will extinguish.
How does oxygen affect how long a candle burns for?
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.
What gas will put a candle out?
If oxygen's excluded, any. As fire needs oxygen to burn, if it lacks this, it won't burn.
Why candle burns longer in oxygen?
Candles burn longer in oxygen because oxygen efficiently supports the combustion process. The heat produced by the flame breaks down the candle wax, releasing fuel molecules which combine with oxygen to continue burning. In contrast, if the candle is in a limited oxygen environment, incomplete combustion occurs and the candle burns at a faster rate.
What happens to a candle if there is no oxygen?
The candle will cease to burn because oxygen is needed for burning. This is why one of the ways to extinguish a flame is to remove its source of oxygen, as described in the fire triangle.
What does a candle need to burn?
Because candles need feul, oil, and oxygen to burn.Without oxygen it will burn out.
What does candle need from air to burn?
A candle requires oxygen (O2) to continue its combustion reaction and produce CO2 and H2O.
What helps a candle to burn?
Oxygen
Does a candle have to have oxygen to burn?
Yes.

How does oxygen Affect how fast a candle will burn?
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.

If a plant and a burning candle are placed under a bell jar will the candle burn?
No, the candle will not burn because the flame will consume the oxygen inside the bell jar, creating a vacuum and extinguishing the flame. Oxygen is necessary for combustion to occur, and without it, the candle cannot burn.
Does air effects length of time for a candle to burn?
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
Why do you think that candle with plant would burn for a longer time?
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
Will an astronaut succeed if he tries burning a candle in the natural environments of the moon?
No, a candle would not burn on the moon because there is no oxygen in the moon's atmosphere to sustain combustion. Oxygen is necessary for fire, and since the moon has very little atmosphere and virtually no oxygen, the candle would not be able to burn.
