Why would a candle burn longer in the open other than in a glass jar?
If the glass jar is sealed, there is a limited amount of oxygen within it. Fire uses oxygen to stay alive. Once it uses up the limited amount of oxygen in the glass jar, it can no longer sustain flame. However, in the open, there is a theoretically unlimited amount of oxygen.
Will a candle burn longer in a large jar then a small jar?
In a large jar as there should be more oxygen.
How will the size of a closed jar affect the burning time of a candle?
Because, if there is a candle in a closed jar it will almost immediately go out. This is because fires cannot be lit without oxygen, and with a closed jar, no oxygen can come in. The fire eats up all of the oxygen, causing it to go out if not quickly exposed to oxygen.
What happens when you put a glass jar on a candle?
a flame needs oxygen to burn so if you put a lit candle in a closed container (like a jar) the oxygen will continue to fuel the fire until there is no more oxygen and the candle will go out
Why are potassium sodium and lithium stored in a jar of oil and not in an empty jar?
Li, Na, & K are all Group '1' metals. They all vigorously react with oxygen. Since oil is a hydrocarbon ( no oxygen present), these metyals remain unreactive. Jowever if stored in an ordinary jar, they would be in contact with oxygen (air( and so would tarnish.
What would happen if you lower a bell jar with the candle inside it withiut any air entering it?
The candle would burn off all the oxygen inside the jar, then the flame would go out as it needs oxygen to burn.
What will happen if you put a jar over a burning candle?
the candle would eventually burn out because it needs oxygen to keep the flame going and when the jar is on top, no oxygen is getting to the fire
What happen if a big and a small burning candle is covered with a big jar?
Once the oxygen was used up, both candles would go out.
A jar contains helium.What would happen if the lid of the jar was removed?
The helium, being lighter than air, would simply rise out of the jar.
How does fire go out if its covered by a jar?
Fire requires oxygen to burn. No oxygen = no flame. When you put a flame in a jar it lives off the oxygen inside the jar for a while. Once you put a lid on the jar, eventually the jar will run out of oxygen and the flame will burn 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
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.
What would happen to the shape of each substance if the jar were broken?
none
Why does a mouse under a jar die?
It dies because it will eventually use up all the oxygen in jar and no oxygen will be able to enter the jar.

What will happen when a jar of hydrogen is inverted on the jar if oxygen and the lid is removed?
The hydrogen will rise to the top of the jar since it is less dense than air. If a flame or spark is present, the hydrogen can ignite and possibly cause an explosion due to the reaction with oxygen in the air. It is important to handle flammable gases like hydrogen with caution.
What would happen if a jar loose fitting lid were placed in a freezer?
What's in the jar? If you mean water, the ice *should* extrude out of the jar a little way without bursting it.
