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 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
Does pure hydrogen burn in the absence of air?
No hydrogen will not burn in the absence of air unless another oxidizer is present.
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
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 does the candle burn for a long time in oxygen?
Candles burn for a long time in oxygen because the wax fuel slowly melts and vaporizes. The vaporized wax reacts with oxygen in the air, causing a continuous supply of fuel to sustain the flame. Oxygen helps maintain combustion, allowing the candle to burn steadily until the wax fuel is consumed.
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.
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.

What does candle need from air to burn?
A candle requires oxygen (O2) to continue its combustion reaction and produce CO2 and H2O.
Why pure NH3 does not burn in air but impure PH3 burn in air?
With traces of P2H4 present, PH3 is spontaneously flammable in air
