Why do candles go out when covered?
because the air current carries away the oxygen, which is needed for a candle to burn.
Why do candles burn in the air?
Burning is a reaction of oxidation, a reaction of oxygen with a substance. Candle components are flammable.
What is the chemical change when a candle is alight?
When a candle is lit, the wax (hydrocarbons) in the candle reacts with oxygen in the air through combustion to produce carbon dioxide and water vapor. This chemical reaction releases heat and light energy, making the candle burn.
What happends to a burning candle if there is no oxygen?
It will simply go out as fire needs to burn oxygen, too. You can see this. Empty and clean an aluminum soda can. Place a burning candle deep in a jar. Pour a teaspoon of hydrogen peroxide in the soda can. Cover and shake upright. Leave the liquid in the can while you slowly pour the carbon dioxide gas into the jar and it puts the candle out by pushing all the oxygen up and out.
Where does a chemical reaction occur on a candle?
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
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
Will a candle burn longer in inhaled air or exhaled air?
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.
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.
What does a candle need to burn?
Because candles need feul, oil, and oxygen to burn.Without oxygen it will burn out.
How does a candle burn in the air?
A candle is able to burn in the air due to the presence of oxygen. The wick of the candle (usually made up of braided cotton) "draws" the wax up to the flame, providing the flame with combustible material to continue burning.
What experiment could you do to prove that oxygen is needed for burnig?
simply cover a burning candle with a glass to cut off the air, then the candle will burn out
Why do candles go out when covered?
because the air current carries away the oxygen, which is needed for a candle to burn.
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 to have wax for it to burn?
No. Not all candles are made of wax. A candle can be made of soap, oil, fat.
what is a beautiful cup in a candle?
What Faraday basically said was that when you burn a candle, you see the formation of a "beautiful cup". This cup is formed as the air near the candle moves upward due to heat of the candle.
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.

Does the blue flame on a Bunsen burner need the air hole open or shut?
It needs to be open to create the hot, blue flame that roars. If the air hole is shut, the flame will burn yellow, similar to a candle.
