- 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.

Does boiling water have oxygen?
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.

Does pepper affect the boiling point of water?
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.
Why would most likely be the temperature of boiling water?
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.
How does boiling water stop the spread of typhoid?
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.
Will boiling water remove oxygen from boiler water?
Boiling water will not remove oxygen from boiler water; it will actually deaerate the water, reducing the dissolved oxygen content. Oxygen removal from boiler water typically relies on mechanical deaeration processes or chemical treatments.
When boiling water what particular gas evaporates first oxygen and hydrogen?
When boiling water, the gas that evaporates first is water vapor (H2O). Oxygen and hydrogen molecules do not evaporate as gases from boiling water, as they remain bonded together to form water vapor.
What is the difference between boiling water and decomposing water?
Boiling water is the process in which water reaches its boiling point and turns into vapor, while decomposing water involves breaking down water molecules (H2O) into its constituent elements, hydrogen and oxygen. Boiling water is a physical change, while decomposing water is a chemical change. Boiling water is reversible, while decomposing water is typically irreversible.
Will boiled distilled water no longer have oxygen?
Boiling distilled water can drive out some dissolved gases, including oxygen. However, distilled water naturally absorbs oxygen from the air, so it will still contain some oxygen even after boiling.
Composition of a water bubble in boiling water?
A water bubble in boiling water is composed of water vapor, which is the gaseous form of water. The bubble forms when water reaches its boiling point and the water molecules evaporate into gas, creating a pocket of vapor within the liquid water.
Does boiling water contain any gasses?
Yes, boiling water can contain gases such as dissolved oxygen and carbon dioxide. When water is heated to its boiling point, these gases can be released as bubbles.
Is the boiling point hydrogen or oxygen colder?
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.
Does boiled water or unboiled water have more oxygen?
Boiled water has less oxygen than unboiled water because the boiling process drives off dissolved gases, including oxygen.
Does boiling decompose water?
No. Boiling water just changes the state of matter. From a liquid to a gas. still 2 hydrogen and still 1 oxygen
Can steel be rusted by cold luke and boling water?
It requires water and oxygen. Cold, lukewarm, or boiling water will do it. Boiling can introduce some other types of errosion/corrosion, also.
Can water be separated into hydrogen and oxygen by boil physical change or chemical change?
Water can be separated into hydrogen and oxygen through a chemical change called electrolysis, which uses an electric current to break apart the water molecules. Boiling water is a physical change that only changes the state of the water from liquid to gas, but it does not separate the water into its component elements.
Does the content of oxygen in water decreases when water is boiled for too long?
When you boil water the oxygen content is reduced to zero. (All gasses are driven out,) Boiling it longer doesn't have much effect.
