When a glass jar is placed over a lighted candle, the flame eventually goes out due to a lack of oxygen. The candle burns oxygen to sustain the flame, and as the jar seals it off, the available oxygen inside the jar is consumed. Without sufficient oxygen, the combustion process cannot continue, leading to the extinguishing of the flame. Additionally, the heat from the flame warms the air inside the jar, causing it to expand and create a slight vacuum, further limiting oxygen supply.

When a glass jar is placed over a lighted candle the flame goes out why does its happen?
A flame uses oxygen in order to burn. By placing a jar over it, it limits the oxygen causing the flame to burn out. That is one reason house fires are dangerous, because fire burn oxygen and we need oxygen to breathe
Why does the light of the candle turn off when the cup cover the candle and the water raises?
the candle light turns off when the cup is placed over the candle and water rushes in due to atmospheric pressure . when cup is placed on the candle all the air goes out and the glass lifts up due to the atmospheric pressure releases from outside of the cup as there is no air inside to balance the pressure exerted out of the cup . thus when the glass lifts up and the water gets into the cup .
What are the tools used in observing the burning candle?
Some tools used in observing a burning candle include a lighter or matches to ignite the candle, a ruler or measuring tool to gauge the height of the candle as it burns, a stopwatch or timer to track the burning time, and a magnifying glass to observe the flame in greater detail.
What is the background of a candle?
A candle typically consists of a wick surrounded by a solid fuel source, like wax. When the wick is lit, the heat from the flame melts the wax, allowing it to be absorbed by the wick and produce light. Candle-making dates back thousands of years, with early candles made from materials such as animal fat or beeswax.

Why does the candle flame goes out when placing a glass over it?
When a glass is placed over a candle flame, it acts as a barrier by cutting off the oxygen supply needed for combustion. Without oxygen, the candle cannot sustain the chemical reaction that produces the flame, causing it to go out.
When a glass jar is placed over a lighted candle the flame goes out why does its happen?
A flame uses oxygen in order to burn. By placing a jar over it, it limits the oxygen causing the flame to burn out. That is one reason house fires are dangerous, because fire burn oxygen and we need oxygen to breathe
Why a candle gets extinguish when a glass is put over it?
When a glass is placed over a candle, the candle flame burns up the available oxygen inside the glass. As the oxygen is used up, the flame is starved of oxygen and eventually goes out. This demonstrates the concept of oxygen depletion leading to extinguishing of the flame.
If you lift the glass tumbler which is placed over a burning candle to 1cm height what hapens?
Lifting the glass tumbler placed over a burning candle to a height of 1cm could disrupt the airflow around the candle, affecting its ability to receive oxygen. This may cause the candle flame to flicker, decrease in size, or even extinguish depending on how much air is allowed to reach the flame.
How does a candle look like it is burning inside a glass of water?
When a candle is placed inside a glass of water, the water absorbs the heat produced by the flame. This heat causes the water to evaporate and rise above the flame, creating the illusion that the candle is burning inside the water. In reality, the candle is burning above the water level.
What happens a candle is placed under a glass container?
Placing a candle under a glass container will cause the flame to consume the oxygen inside the container. As the oxygen is used up, the flame will eventually extinguish due to lack of oxygen, creating a vacuum inside the container.
Why does a candle extinguish itself after being covered with a glass?
The burning flame on a candle needs three things to continue burning: 1) fuel, which it gets from the wick 2) heat, which comes from lighting the candle 3) oxygen Without any one or more of these three things, the candle will no longer continue to burn. In the case where a candle is covered with a glass, the candle quickly uses up the oxygen inside the glass. once all of the oxygen is gone, the flame will burn out.
How do you prove that candles use oxygen?
Light the candle and put a glass jar over it. Watch the flame of the candle closely. When the flame goes out, this means that the flame must have oxygen to burn the candle. This is how candles use oxygen.
When a burning candle is covered with a glass it get extinguished why?
When a burning candle is covered with a glass, the oxygen within the covered space gets depleted as the flame consumes the available oxygen. Without sufficient oxygen, the candle flame is unable to sustain combustion and gets extinguished.
If you will take some water in a shallow bowl and insert a candle and insert a glass over the lighted candle soon the flame extinguishes the water level inside the glass will rises up find out why?
The main cause is that the glass is covering warmer air, heated by the flame, in the beginning. When the flame extinguishes, the air inside the glass starts to cool. Universal Gas Law: PV/T = a constant. Assume P = a constant too (the atmosphere pressure has changed little). Since the air temperature drops, the volume has to shrink too. The water rises up the glass a little to equalize the pressure.
What happens when you cover the top of a glass that has a burning candle inside?
When you cover the top of a glass with a burning candle inside, you restrict the flow of oxygen to the flame. This causes the flame to consume the available oxygen within the glass, leading to the extinguishing of the flame due to lack of oxygen. Additionally, the heat and gases produced by the burning candle may build up within the glass.
Why do candles go out when we put glass jars over them?
Oh, dude, it's like, science and stuff. So, when you put a glass jar over a candle, it messes with the oxygen flow that the flame needs to keep burning. It's like trying to breathe with a plastic bag over your head - not a good idea if you want to stay alive, you know? So yeah, candles need oxygen to burn, and glass jars are like, "Nope, not today, candle."
