Question: What Is The Chemical Name Of Fire?

What is the chemical formula for fire?

The heat of the flame will keep remaining fuel at ignition temperature.

The flame ignites gases being emitted, and the fire spreads.

As long as there is enough fuel and oxygen, the fire keeps burning.

Fuel + oxygen (from the air) = combustion products (mainly CO2 + H2O) + heat energy..

Is Black Fire Possible?

Flames emits light and heat, so it seems impossible to make black fire. However, you actually can make black fire by controlling the wavelengths of absorbed and emitted light.

Is white fire real?

White is an elusive fire color because the fuel that supports a flame burns with its own characteristic spectrum. But, with a little chemistry know-how, you can get white fire.

Is the Sun Fire?

The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. … Hydrogen really doesn’t burn, it fuses, into helium. So no oxygen is required!

Can hydrogen be burned?

There are generally two ways hydrogen can burn: It can be used in nuclear fusion, in powerful reactions such as the ones that cause stars to burn, or it can combust on earth with the help of the oxygen-rich atmosphere.

What is a Class K fire?

A Class K fire extinguisher is used on fires involving cooking media (fats, grease, and oils) in commercial cooking sites such as restaurants. … Saponification takes place when alkaline mixtures, such as potassium acetate, potassium citrate, or potassium carbonate, are applied to burning cooking oil or fat.

What are the 5 main types of fire extinguishers?

There are five main types of fire extinguishers:Water.Powder.Foam.Carbon Dioxide (CO2).Wet chemical.

What are the 4 types of fire?

Classes of fireClass A – fires involving solid materials such as wood, paper or textiles.Class B – fires involving flammable liquids such as petrol, diesel or oils.Class C – fires involving gases.Class D – fires involving metals.Class E – fires involving live electrical apparatus. (More items…

Does fire need air?

Any flame requires three ingredients: oxygen, fuel and heat. Lacking even one, a fire won’t burn. As an ingredient of air, oxygen is usually the easiest to find. (On planets such as Venus and Mars, with atmospheres containing far less oxygen, fires would be hard to start.)

Do humans burn or melt?

Humans are animals. It depends on the conditions – animal flesh would also “melt” under the right conditions, and human flesh usually burns instead of melting.

What is type of fire?

There are four classes of fires: Class A: Ordinary solid combustibles such as paper, wood, cloth and some plastics. Class B: Flammable liquids such as alcohol, ether, oil, gasoline and grease, which are best extinguished by smothering.

What are the 6 classes of fire?

There are 6 different classes of fire, and each should be attacked in a different way.Class A (Solids) Class A fires are fires involving solids. … Class B (Liquids) Class B fires are fires involving liquids. … Class C (Gases) … Class D (Metals) … Electrical Fires. … Class F (Cooking Fats & Oils)

How is fire made 1st grade?

Fire is a chemical reaction that occurs when heat and a fuel source combine with oxygen in the air, creating flames and giving off light and smoke. Fire is created by a chain reaction involving heat, oxygen and fuel.

What is full form of pass?

Discharge the extinguisher within its effective range using the P.A.S.S. technique (pull, aim, squeeze, sweep).

What makes a fire?

Fire is the result of applying enough heat to a fuel source, when you’ve got a whole lot of oxygen around. As the atoms in the fuel heat up, they begin to vibrate until they break free of the bonds holding them together and are released as volatile gases. These gases react with oxygen in the surrounding atmosphere.

Where does fire come from?

Typically, fire comes from a chemical reaction between oxygen in the atmosphere and some sort of fuel (wood or gasoline, for example). Of course, wood and gasoline don’t spontaneously catch on fire just because they’re surrounded by oxygen.

What Cannot be burned by fire?

Riddle: What can’t be burned in fire, nor drowned in water? Answer: Ice.

What are 5 classes of fire?

Fires can be classified in five different ways depending on the agent that fuels them: Class A, Class B, Class C, Class D, and Class K. Each type of fire involves different flammable materials and requires a special approach.

Are black flames the hottest?

The color of a fire can change based on what is burning. If you found a chemical or element that burned with a very dark flame (though very likely not ever black), you could have a flame that was quite dark. In this case, the flame would not necessarily be any hotter or cooler than any other.

Is fire a oxygen?

Fire is a chemical reaction in which energy in the form of heat is produced. When forest fuels burn, there is a chemical combination of the oxygen in the air with woody material, pitch and other burnable elements found in the forest environment. This process in known as Combustion.

Can fire exist without oxygen?

A fire cannot burn without oxygen. … It should be noted that in the presence of carbon, nitrogen and oxygen, stars heavier than the Sun may burn hydrogen to helium by using the C, N and O as catalysts. Even in these stars, however, an absence of oxygen does not prevent nuclear burning.

Is purple fire real?

Purple flames come from metal salts, such as potassium and rubidium. … Purple is unusual because it’s not a color of the spectrum. Purple and magenta result from a mixture of blue light and red light. For this project, the fire color comes from the emission spectra of safe chemicals.

What are the 3 elements of fire?

Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.

What will not burn?

Wherever any substance is put in fire it burns and changes into ash. But asbestos is one such material that does not burn in fire. That is why the fireman wear clothes made from asbestos when they enter the burning house. In fact their clothes, shoes, gloves, helmets etc.

Can fire burn forever?

“As long as there is a fuel supply and oxygen to supply it, a fire can burn indefinitely,” said Steve Tant, policy support officer for the Chief Fire Officers’ Association operations directorate. … “They have the right conditions, particularly if they are on a coal seam where there is a constant fuel source.
