Why does water put out fire if it has oxygen and hydrogen?

Water puts out fire by creating a barrier between the fuel source and the oxygen source (it also has a cooling effect which has to do with the energy required to convert liquid water into water vapor). It does this because it is a completely, 100\% oxidized material. This smothers the fire.

Why water is used for fire extinguisher as it made of hydrogen and oxygen while both are helping in production of fire?

This means that when water H2 O is applied to a developing fire in ordinary combustible materials, the water does not break down into the basic elements of Hydrogen (H) and Oxygen (O), both of which would encourage fire growth. Water’s surface tension allows it to exist from small droplets to a solid stream.

Does hydrogen make fire explode?

Hydrogen used in the fuel cells is a very flammable gas and can cause fires and explosions if it is not handled properly. Hydrogen is a colorless, odorless, and tasteless gas.

Is hydrogen and oxygen flammable?

Hazards: Hydrogen gas is very flammable and yields explosive mixtures with air and oxygen. The explosion of the mixture of hydrogen and oxygen is quite loud.

Can oxygen be flammable?

Oxygen is not flammable, but it can cause other materials that burn to ignite more easily and to burn far more rapidly. The result is that a fire involving oxygen can appear explosive-like.

How do you put out a hydrogen fire?

The only sure way of handling a hydrogen fire is to let it burn under control until the hydrogen flow can be stopped. Close the block or isolation valves close to the hydrogen container by remote operation from a safe distance. Use water sprays to extinguish any secondary fire and keep the fire from spreading.

Is oxygen flammable or explosive?

Does fire need hydrogen?

It is true that hydrogen is an explosive gas, and it also needs oxygen to burn. If you put together suitable volumes of hydrogen and oxygen and provide a spark to start the reaction, one oxygen atom will combine with two hydrogen atoms, and will release energy in the process.

Can water explode in a fire?

For instance, hydrogen sulfide is made of hydrogen gas (an odorless explosive gas) and sulfur (an odorless yellow metal), but in combination it produces something which stinks of rotten eggs! For water to contribute to a fire, it would have to be broken down into hydrogen and oxygen. This occurs only during electrolysis.

Why can’t a hydrogen atom start a fire?

So a hydrogen atom by itself wont start or feed a fire. It needs to be joined to another hydrogen atom. Then in the fire along comes two oxygen atoms that you forgot to breathe in, and they burn together forming H2O. The bonds that hold the two hydrogen atoms to the oxygen are very stong. The oxygen likes to hold onto atoms really tight.

Why does hydrogen need oxygen to burn?

It is true that hydrogen is an explosive gas, and it also needs oxygen to burn. But the key point lies in this question: What is burning? The answer is that burning is the process of reacting with oxygen to produce energy.

What happens to water when it is burned?

The answer is simple, if the proportions were right (one volume of oxygen for two volumes of hydrogen gas) all you get is water! Thus, water is _already burnt_. It is the “ashes” of hydrogen after it has burned. If you wish to burn it again, you have to separate oxygen and hydrogen. But, to do that, you need to supply as much energy as is…
