Why is a burning candle extinguished by a fire extinguisher?
Like any other fire, a burning candle requires fuel, heat, oxygen and a chemical reaction. If you use a fire extinguisher, it typically removes the heat or oxygen from the process, thus stopping the fire.

What do fire extinguishers remove from the fire triangle?
It depends upon what kind of extinguisher it is. Water, for example, removes the heat from a fire by turning into steam and by removing available air/oxygen from the flames. Other extinguishers remove the oxygen from the fire or change the chemical reaction to stop the fire from converting the fuel to a flammable substance with the available heat.
What type of extinguisher is most suitable for dealing with fires involving carbonaceous materials?
The most suitable extinguisher for dealing with fires involving carbonaceous materials, such as wood, paper, and textiles, is a Class A fire extinguisher. These extinguishers typically contain water or foam, which effectively cools the burning material and removes heat from the fire. Additionally, dry chemical extinguishers labeled for Class A fires can also be used, as they can interrupt the chemical reaction of the fire. It's important to ensure the extinguisher is rated for Class A fires specifically.
What is removed when putting out a forest fire?
fire is removed and small pieces of fire petrol are covered with the fire extinguisher.
Why do you put heat oxygen and fuel together in a fire triangle?
IF either of the 3 is missing, the fire will can not continue to burn.The triangle illustrates the rule that in order to ignite and burn, a fire requires three elements: heat, fuel, and an oxidizing agent (usually oxygen). The fire is prevented or extinguished by removing any one of them. A fire naturally occurs when the elements are combined in the right mixture.Throwing water on the fire removes the heat.Throwing a blanket or using a carbon dioxide extinguisher removes the oxygen.In the case of a wood fire, removing pieces of wood ( spreading out the wood) removes the fuel

How do you remove heat from fire?
You can remove heat from a fire by cutting off its oxygen supply, using a fire extinguisher, or dousing it with water. Removing the heat source or covering the fire with a non-flammable material can also help extinguish the fire by reducing heat.
