Question:define fire in short way?
answer: Fire is a chemical reaction that gives off light and heat. It is an example of the chemical process. Forest fires are very harmful. They can destroy a huge area in a matter of minutes. Every year people die by accident from fire.
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. .The combustion process or �fire� is sometimes called �rapid oxidation.
Type of fire
There are 6 different types of fire, and each should be attacked in a different way.
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.
INVENTION OF FIRE
The oldest unequivocal evidence, found at Israel's Qesem Cave, dates back 300,000 to 400,000 years, associating the earliest control of fire with Homo sapiens and Neanderthals. Now, however, an international team of archaeologists has unearthed what appear to be traces of campfires that flickered 1 million years ago.
