In a combustion reaction, a compound or element reacts with oxygen, releasing a large amount of energy in the form of light and heat.
The history of fires goes back to the 17th century. They were called, “Fire buckets”. They came into existence because there was no fireman. Fire buckets were people organizing themselves like a human chain with buckets passing around. There was at least two to three buckets full of
The most common source of heat for the purpose of firefighting comes from chemical reactions. When something burns, it is the result of a chemical reaction where heat is being released. Pyrolysis is the "decomposition or transformation of a compound caused by heat."(Coleman, et al. 81)
There is big debate as to exactly when humans first discovered the controlled use of fire. Many people ask if they Uncontrolled fire was terrified in early life and still has the power to scare today. Forest fires, or houses being burnt to the ground are still huge problems. However, t were able to start it, how did they control it. We do not have any honest answers but they may have used pieces of flint to create sparks. They could have rubbed two sticks together to start a fire. The conditions of their sticks should be good for a fire.
We repeated this for a total of 6 known substances and 3 unknown substances. We also made a table for each element showing the color of the flame that we saw,
In the incipient stage heat and oxygen are combined and ignite creating the fire and initial point of fire. The growth stage there are several factors that can determine who large a fire becomes such as if there are any highly flammable items or combustibles in the area and the height of the ceiling creating thermal layering. Once a fire has reached its maximum potential it is now in the fully developed stage and is extremely hot and dangerous at that point. Decay occurs in a fire while it is being tamed or extinguished. The decay stage can be dangerous because if there are items that can cause a combustion that have not been ignited yet it can make a firefighter think they are out of the woods and safe and then a backdraft occurs because of the oxygen being reintroduced to the
I have always had a fascination with fire, and like you can guess, that particular fascination has gotten me into trouble with burning myself, my clothes, and in this particular stories my neighbor’s lawn.
It blazes with passion, burning everything that'll stand in its path, only to burn quickly or to die down slowly.
Nobody knows what caused the Triangle Fire, and maybe no one ever will. Although, there is a writer that described the events so thoroughly that the images make it seem like we were there. This writer’s name is Albert Marrin. The way he is making these images so vivid is something that many amazing writers use. It is called figurative language. He uses many forms of figurative language in his describing of the Triangle Fire. The main reason he uses them was to make the writing more impactful. In other words, instead of using everyday words, he uses metaphors that allows us to comprehend the text, and it also allows us to relate to it. That is why the use of these creating writing elements makes this non-fiction text so impactful. When the
Heat per Unit Area is a measurement of rate of spread and flame length. The equation is HA = (60 IB) / R “IB” is the fireline intensity (kJ m-1 s-1). “R” is the rate of spread (m-1 s-1).
On the actual day of the fire, the fire planners will again check such conditions as wind and moisture content in the vegetation. The wind direction will determine where the fire is started. Fire crews start the burn with a device called a drip torch. A drip torch is a can of fuel with a flame-carrying wick at the end. When the crewmember tilts the wick toward the ground, a flame streams out and ignites the vegetation. Most of the effort that goes into a prescribed fire is making sure that it is contained in the boundaries set for the fire. Firefighters and fire suppression equipment are near the site if the fire grows out of control (www.nps.gov/wica/fir-why.html, pgs. 1-3).
Fire is explained in a tetrahedron of necessary requirements a fire needs before it is able to spring to life. First, is sufficient fuel. Different types of fuel coincide with different types of terrain. In dry, sparse areas, dead grass and shrubs provide the best fuel. In lush, green forests, pine needles, leaves, twigs, and other such things typically underfoot makes for the best fuel . Second, is an oxidizing agent. This could be the oxygen
Constant: The flame (heat) Research When a solid flammable substance is heated it burns slowly because the energy being applied to the object is being dissipated as fast as it is being applied but if the same material is grinded into a fine powder and then mixed with the air in order to make a dust cloud and then the dust ignited the substance will burn quickly and the energy is being released
Fuel is a less combustible material that burns slow and steady once lit, like tree trunks, coal and oil. To start a fire, first the tinder is lit on fire. Then the kindling on top of it catches fire. When the kindling produces enough heat, the fuel will catch on fire. When all three ingredients are present in the correct amount, oxygen, heat, and fuel will start a fire and keep it burning.
