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.
Which one takes longer to burn rubber or a candle?
a candle takes longer to burn but it smells nicer, especially if it is a scented candle
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
How do you make a candle burn green?
if you burn copper sulphite
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
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.
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.

Would a large plant and a burning candle placed under a bell jar will the candle burn the plant because of the plant is giving off carbon dioxide?
The candle will burn BUT it is because the plant is giving off OXYGEN and is TAKING IN carbon dioxide.
What would happen if you lower a bell jar with the candle inside it without any air entering it?
it would burn out in few seconds. if you take away the air, you also take away the oxygen in it (the air). and fire need oxygen to burn. simple explanation (sorry for bad spelling, I'm danish)
