What else can I help you with?
What would happen if you lower a bell jar with the candle inside it withiut any air entering it?
As the candle burns, it consumes oxygen and releases carbon dioxide. If the bell jar is sealed, the oxygen inside gets used up and the candle flame will eventually extinguish once oxygen levels drop too low to sustain combustion. The remaining air will become enriched with carbon dioxide from the burning candle.
Who used a bell jar candle and a plant to show plants give off something that candles need to burn?
Joseph Priestley used a candle and a plant under a bell jar to show that plants release oxygen, which is essential for combustion, allowing the candle to burn. This experiment demonstrated the process of photosynthesis, where plants convert carbon dioxide into oxygen using light energy.
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)
How does the shape of a candle affect how fast it burns?
The shape of a candle can affect how fast it burns as it impacts the surface area exposed to heat. Candles with a larger surface area, like pillars or jar candles, tend to burn faster because they have more wax exposed to the flame. Taper candles, with a smaller surface area, burn slower as the wax melts more gradually.
Why do candles need oxygen?
YES. The available amount of oxygen in air regulates the candles burn. The oxygen burns with the paraffin wax. Both are consumed. A mix of more oxygen will burn faster and hotter. Rapid oxydation is dangerous.
Will a candle burn longer in a large jar then a small jar?
Yes, a candle in a large jar will typically burn longer than a candle in a small jar. This is because the larger jar provides more oxygen for the flame, which helps the candle burn more efficiently. Additionally, the larger jar can contain more wax, extending the burn time.
Does the temperature of a candle jar inhibit growth of psychrotrophs What is the average temperature inside candle jar and how long does it take flame to burn out?
The temperature of a candle jar inhibits the growth of psychrotrophs, and the average temperature inside the candle jar is 30 degrees Fahrenheit.
How long does it take for a candle to go out in a bell jar?
The time it takes for a candle to go out in a bell jar depends on the size of the jar, the amount of oxygen present, and the size of the candle. Generally, a candle will burn out more quickly in a bell jar due to limited oxygen supply, which is necessary for combustion to occur.
How does the size of the jar affect the burning time of a candle?
The Smaller the jar the less oxygen, the bigger the jar the more oxygen, and since the candle lives of oxygen the biggest jar with the candle in it will take the longest to burn.
Can you burn a candle inside a jar?
For a short time with the lid on or for much longer with the lid off.
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 is the relationship between the size of the jar and the time taken for the candle to go of?
I assume you are thinking about a situation where the jar is airtight.In this case, a larger jar will have more air in it, and therefore more oxygen; the candle will be able to burn longer in a larger jar. I would expect the time it burns to be roughly proportional to the volume of the jar.
Can a candle in a jar last forever?
No, a candle in a jar will not last forever. The candle will eventually burn out as it consumes the wax and wick. The duration of the candle depends on factors such as the size of the candle, the quality of the wax, and the environmental conditions.
What is the relationship between the size of the jar and the time taken for the candle to go off?
I assume you are thinking about a situation where the jar is airtight.In this case, a larger jar will have more air in it, and therefore more oxygen; the candle will be able to burn longer in a larger jar. I would expect the time it burns to be roughly proportional to the volume of the jar.
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 long can a candle stay lit in a upturned jar?
The duration a candle stays lit in an upturned jar depends on factors like the size of the candle, the amount of oxygen available for it to burn, and the quality of the wick. In general, a candle may struggle to stay lit for more than a few minutes in an upturned jar due to limited airflow.
Will a candle burn twice as longer in an inverted liter jar than in a half-liter jar?
Yes. There is twice as much oxygen in a liter jar.
