What are the chemical 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 elements are in a combustion?

Three things are required in proper combination before ignition and combustion can take place—Heat, Oxygen and Fuel.

• There must be Fuel to burn.
• There must be Air to supply oxygen.
• There must be Heat (ignition temperature) to start and continue the combustion process.

What is the physics of fire?

Fire is a chemical reaction ,some times hot enough to turn the gas around it into plasma which you can basically think of as a hot ionized gas. You can show that fire can form plasma by putting negatively charged plate on the left of a flame and a positively charged plate on the right of the flame.

What are the five categories of fire?

Classes of fire

• Class 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. (

Which gas is required for burning?

Oxygen is required for burning or combustion to take place.

What type of combustion is fire?

Combustion is another name for burning. It is an example of an exothermic reaction, a reaction that releases energy to the surroundings. This is mostly thermal energy, but light energy and sound energy are also released….Combustion reactions.
