What control the process of burning?
The most common method to control a Class-A fire is to remove heat by spraying the burning solid fuels with water. Another control method would be to reduce the oxygen content in the immediate vicinity of the fire (i.e., “smother” the fire), such as by the introduction of an inert gas such as carbon dioxide.
What type of chemical reaction that involves process of burning?
Combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.
Which gas support the process of burning?
Oxygen is Necessary for Burning (or Combustion) Air is known as a supporter of combustion. When a substance burns in air, it is actually the oxygen present in air which is used up in the process of burning.
Why burning is a chemical process?
The process of burning (as opposed to evaporating) is a chemical reaction, a chemical change. The wax molecules are undergoing a chemical change; they are changing into different molecules by reacting with a substance in the air.
Does air support burning?
After few minutes the candle is extinguished. As the supply of air is stopped due to glass jar the burning of candle is also stopped. This experiment proves that air supports burning.
Which gas does not support burning and is used in fire extinguisher?
Carbon dioxide gas
Complete answer: Carbon dioxide gas does not support combustion. It displaces oxygen so that oxygen cannot come in contact with fire. Thus, carbon dioxide gas stops the supply of oxygen thereby removing oxygen from the fire triangle. In fire extinguishers, carbon dioxide gas is stored under very high pressure.
What is the chemical reaction of burning coal?
|reaction||effect of increase in temperature||heat of reaction|
|carbon + oxygen = carbon dioxide (combustion)||—||exothermic|
|carbon + carbon dioxide = carbon monoxide (Boudward)||to right||endothermic|
|carbon + water = carbon monoxide + hydrogen (water-gas)||to right||endothermic|
What is the first thing you should do if you discover a fire?
If You Discover a Fire …
- Pull the fire alarm and call for help.
- Alert people in the area to begin evacuation.
- Close doors to confine the fire.
- Go to your designated assembly area, away and upwind from the building.
How does the process of burning produce heat?
Combustion is the process of burning. element Each of more than one hundred substances that cannot be broken down into simpler substances. fire The burning of some fuel, creating a flame that releases light and heat. fuel Any material that will release energy during a controlled chemical or nuclear reaction.
How does the burning of a candle release energy?
Interestingly, a candle releases energy through the same kind of reaction that your body uses to obtain energy. Hold your breath for a moment. What is your body craving? This is the same substance the candle needs to burn in a chemical change that we call combustion.
What do you need to know about the combustion process?
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. The Sun is the major source of heat.
What makes a fire burn and what makes it burn?
In other words, when something burns, there’s no un-burning it. Fire also is a glowing reminder of the oxygen that pervades our world. Any flame requires three ingredients: oxygen, fuel and heat. Lacking even one, a fire won’t burn.
