How is fire made?
There is more to fire than just the emission of heat and light. Fire, simply put, is a chemical process of combustion involving the oxidation of a fuel source at a high temperature. It releases energy and produces heat and light. Flames are produced following the chemical reaction between oxygen and another gas.
How is fire created short answer?
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. Fire begins with ignition.
What three things are needed for fire to be created?
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.
How do things burn?
Burning is a chemical process by which two atoms or molecules will combine with each other. In burning, the two atoms or molecules will combine and release energy. When the molecules combine and release energy, it is released in the form of heat and often light. …
Can you make fire without oxygen?
Without sufficient oxygen, a fire cannot begin, and it cannot continue. With a decreased oxygen concentration, the combustion process slows. Oxygen can be denied to a fire using a carbon dioxide fire extinguisher, a fire blanket or water.
What are 5 causes of fire?

- Heating. Portable heaters are the second-leading cause of home fires and home fire injuries.

When did humans first learn to create fire?
“Fire was first controlled by humans anywhere from about 230,000 years ago to 1.4 or 1.5 million years ago, depending on which evidence you accept as definitive”. Evidence for the use of fire by Homo erectus beginning some 400,000 years ago has wide scholarly support.
How did humans create fire?
Thus, humans encountered and were aware of fire, and later its beneficial uses, long before they could make fire on demand. The first and easiest way to make a fire would have been to use the hot ashes or burning wood from a forest or grass fire, and then to keep the fire or coals going for as long as possible by adding more combustible material.
How and when did humans discover fire?
Historians do not know for sure just how fire was discovered, but most believe that humans first saw fire after lightning struck a tree during the Lower Paleolithic age. Soon, humans discovered that it was possible to not only use the flame for heat and light, but also to cook food.
Who was the first human to use fire?
Homo erectus, the early human beings, were the first to harness fire about a million years ago. In spite of the availability of the advanced fire-fighting systems, fires have very often gone out of control,almost all over the globe in almost all phases of history.
