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.
What helps a candle to burn?
Oxygen
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.
What does a candle need to burn?
Because candles need feul, oil, and oxygen to burn.Without oxygen it will burn out.
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.
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.
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
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.
How candle can burn in underwater?
A candle can burn underwater if it is placed in a container that keeps the water out, allowing oxygen to reach the flame. The candle's wick needs to be exposed to the air for combustion to occur, as fire requires oxygen to burn. However, if the candle is fully submerged without any air access, it will extinguish quickly due to the lack of oxygen. Special setups, like using a bell jar or a similar apparatus, can enable a candle to burn underwater while still providing an oxygen supply.
Does a candle need oxygen to burn?
Yes, a candle needs oxygen to burn. When the wick is lit, it melts the wax, which vaporizes and combusts, reacting with oxygen in the air to produce heat and light. This process is known as combustion.
