Why does fire stop under water?
Fire needs oxygen from the air just like we do. When water gets poured on it, it suffocates and goes out.
A candle is covered with a flask and the flame goes out why?
When the candle flame is covered with a flask, it creates a closed system where the oxygen supply is limited. The flame requires oxygen to sustain combustion, so when the available oxygen is used up, the flame goes out. The process is known as oxygen depletion, and it happens when the flammable material (wax) fails to receive sufficient oxygen to continue burning.
Why does the water rise in a bell jar with a burning candle?
People often think that the reason is because the oxygen gets burned up, creating a vacuum into which the water is sucked, but this is not true. The reason is that the candle heats up the air in the jar, which causes it to expand. The expanding air is pushed through the water at the bottom. Note that at this stage the candle goes out. There is now no flame to heat the air and so it cools down, which makes the air shrink. This is what creates the vacuum that "sucks" the water up.But the oxygen is burned up, so doesn't that reduce the volume of the gas?Yes, the oxygen is burned up, but the chemical reaction between the candle wax and the oxygen produces carbon dioxide of roughly equivalent volume.Does the flame go out because the oxygen gets used up?Actually no. You can show that not all of the oxygen is used up when a candle burns in a bell jar by putting a mouse in the jar, which will stay alive. In fact the changing dynamics of the gases in the jar (increasing carbon dioxide produced in the combustion of wax, decreasing oxygen as it is used up in the combustion) contrive to prevent adequate oxygen from reaching the flame for the combustion reaction to continue.
Where does oxygen go after its in your mouth?
After the mouth (or nose), oxygen (as part of the air) goes down your trachea, into the bronchi, and through the bronchioli, into the alveoli, where it enters the blood and gets taken via the blood to the various parts of your body.
What is oxygen-carbon dioxide cycles?
the carbon dioxide oxygen cycle is how a human breathes out carbon dioxide and it goes to a plant and the plant breathes out oxygen and it goes to the human and that's how they get energy
What happens to a candle in a spacecraft?
It goes out since it has no Oxygen to aide in Combustion.
Where does oxygen go once it gets into the lungs?
the oxygen goes to the air sacs inside of the lungs.
Where does get its oxygen?
the oxygen in your blood comes from the air you breath in . It goes in through your mouth into the lungs and the oxygen gets taken out from the lungs into the cappilaries.
Why do some parts of the heart are red and some are blue?
the blue parts are filled with blood without oxygen, it goes in the heart, to the lungs and gets oxygen from the lungs, then they become red, goes back to the heart and goes to areas of your body in need of oxygen.
Why candles goes out faster with increased height?
the higher you go with the candle the less oxygen there is and fire needs oxygen or it will go out
Where the blood gets oxygen from?
Blood gets oxygen from the lungs. Every time you breath, the oxygen you've inhaled goes into sacs in your lungs called alveoli. The oxygen is diffused into the blood and the blood diffuses carbon dioxide into the alveoli. The carbon dioxide is then exhaled
What happens to the oxygen that is formed from the breakdown of water?
The O from H2O goes to form Oxygen as O2 which is a gas and gets mixed up in the air
How do you regulate the size of a flame when using a Bunsen Burner?
by limiting the amount of oxygen you can get incomplete combustion where the flame is coolest and complete where it goes blue and is bare hot
Why do mountaineer's climbing high mountains carry oxygen cylinders with them?
The higher you go up away from the Earth's surface, the less oxygen can be found in the air and more of gases we don't need to breathe in. So, as the mountaineer goes higher up, breathing becomes harder and your body works slowly, reducing reaction times. By carrying an oxygen tank, the mountaineer can always be breathing the perfect concentration of oxygen they need at all times.
What happens when a oxygen sensor goes bad?
When an oxygen sensor goes bad a car will burn gas at a higher than normal rate because it will not be producing as much power as before. The oxygen sensor checks the amount of exhaust.
Why would a rising mass have low pressure?
It would because the higher it goes the lower it gets
What organ converts blood from oxygen-rich to oxygen-poor?
oxygen rich blood gets pumped out of your heart to your arteries which carries the blood to your muscles. then your muscles use the oxygen. oxygen poor blood goes into your veins to go back into your heart. then it goes through a cycle that takes your blood to your lungs, to get oxygen. this process is repeated.
