There are two different ways to ask this question, each dealing with two different ways that water can "have" oxygen in it. It is important to understand the question being asked because each interpretation has a different answer. 1. Does boiling water contain dissolved oxygen? 2. Does water contain oxygen? The answers: 1. No, boiling water does not contain dissolved oxygen. The hotter a substance is, the more energy the molecules have. There are gases such as carbon dioxide (CO2) and oxygen (O2) dissolved in cold water. As the temperature increases, these gases gain energy which lets them escape from the liquid water in which they are trapped. To relate this phenomenon to something encountered in daily life, a cold can of Coca-Cola has more fizz than a warm one. The fizz is the result of gases escaping from the cold liquid. The warmer Coca-Cola does not contain as much dissolved gas, so it is "flat." 2. Yes, water contains oxygen. The molecular formula for water is H2O, meaning that there are two covalently bonded hydrogens to each oxygen. Change this formula, and you don't have something that can be called "water" anymore. A common misconception is that the process of boiling creates oxygen and hydrogen gases (O2 and H2), which is simply not true. The act of boiling water imparts energy to the liquid water molecules. This energy is enough to break the hydrogen bonds that hold the water molecules together in liquid form. Once these bonds are broken, the water molecules vaporize and go from being H2O (liquid) to H2O (gas). Therefore, the vapor produced as water boils is water vapor. Before the boiling point is reached, you can see the dissolved gases initially present in the cold water (for example, CO2 and O2) forming bubbles and rising to the top. Remember, these were initially present-- they are not a result of the covalent O-H bonds in water being broken as part of the boiling process. The covalent O-H bonds are not broken during boiling, only water vapor is formed.
Water is able to dissolve some gases of which Oxygen is one. At 25 deg C it contains approx. 8mg/L. i.e. not very much; but essential to marine life. As you raise the water temperature the Oxygen is less soluble and is driven out till at a high enough temp. all the O2 is removed. But this is NOT the same O2 that the water is made from i.e. H2O. To break this down requires much more energy e.g. by Electrolysis.
Yes.
Boiling water will remove most, but not all, of the DISSOLVED oxygen. There will still be traces.
Also (if this was a trick question) oxygen is one of the atoms in the water molecule. If you remove the oxygen, it's not water any more.
When you boil water, you are breaking the attractive force between water molecules. The bond holding the hydrogen and oxygen atoms to each other within a water molecule are much stronger.
Not from the water molecule, No.
But boiling will remove any oxygen dissolved in the water
Boiling water does not change the molecular structure of it. Therefore, the answer to your question is no. Boiling water does not decrease the oxygen levels in it.
Dissolved gases are easily released at high temperature.
As it is boiling, yes!
No,boiling water does not have oxygen . Cold water molecules move slowly meaning there is space between the molecules for more oxygen to dissolve. Hot water molecules move rapidly meaning the space between the water molecules is less avalible for the oxygen molecues to dissolve into.

Pepper has the least effect on the temperature or reaction to boiling water ,As well pepper does not dissolve in boiling water like other grains.
Which is most likely be the temperature of boiling water? 100oC is the boiling point of pure water - when water is boiling, it stays at a constant temperature until all of it is evaporated.
Typhoid bacteria is often spread through water and cannot survive high temperatures like the 100oC of boiling water so by boiling the water the typhoid bacteria is killed and the chance of transmission is reduced.
When boiling water, the elements do not seperate. The only substance that evaporates is water as 'steam'.
Oxygen has a lower boiling point than water.
No,boiling water does not have oxygen . Cold water molecules move slowly meaning there is space between the molecules for more oxygen to dissolve. Hot water molecules move rapidly meaning the space between the water molecules is less avalible for the oxygen molecues to dissolve into.
when vapour pressure>/ = atmospheric pressure then called boiling. sepration of water in hydrogen and oxygen is called decomposition.
A water bubble consists of oxygen. Bubbles occur because of escaping air from liquids when heated. There is plenty of oxygen in water and that is why the bubbles are mostly oxygen.
No. Boiling water just changes the state of matter. From a liquid to a gas. still 2 hydrogen and still 1 oxygen
It requires water and oxygen. Cold, lukewarm, or boiling water will do it. Boiling can introduce some other types of errosion/corrosion, also.
Water cannot be separated into hydrogen and oxygen by boiling. Boiling is a physical change which means the molecule doesn't change at all--liquid water and water vapor are both H2O. Water can be separated into hydrogen and oxygen using electricity, this would be a chemical change.
It is simply the water that freexes. Water is not simply a mixture if hydrogen and oxygen. The two elements are bound together to form water molecules. So it must be treated as its own substance. The behavior of water cannot be explained using the behavior of elemental hydrogen or oxygen. Its properties are different from its constituent elements.
When you boil water the oxygen content is reduced to zero. (All gasses are driven out,) Boiling it longer doesn't have much effect.
Oxygen has the lowest boiling point of these. It is far below the boiling points of the others.
definitely oxygen boils at about 90.2 kelvin (degrees C above absolute zero)
