Review of Literature
Fire has been around for many years. As the years passed, we have thought of and invented many things that create and maintain fires for hours and hours. We take having fire instantly for granted. But what if we didn’t have a gas stove or gas grill anymore? We would have to use wood. People have been using wood for years, but do you know which kind of wood to use so that your fire burns for the longest amount of time possible or for the shortest amount of time?
Fire is chemical reaction between oxygen and a type of fuel. To make a fire you must heat the fuel to its ignition temperature. Things that can light wood are matches, focused light, friction, etc… These things heat the wood to its ignition temperature, but different types of wood can have an unsimilar ignition temperatures (Harris, n.d.). Each type of wood used in this experiment will have a varying ignition temperature because they are different types of wood. When the fire is burning the wood, “the fact that the chemical reactions in a fire generate a lot of new heat energy is what sustains the fire” (Harris, n.d.). When the fire has no more fuel (wood) to create the chemical reaction with, then there will be no more heat energy to produce a fire.
Hardwood and softwood trees make trees different because trees get these names by the way they reproduce or release seeds. Hardwoods trees are angiosperms, which are plants that make seed with some sort of covering for the seeds (What is the difference between a hardwood and a softwood?, 2001). Some examples are the fruit trees that have seeds inside or an acorn that has a shell over the nut. Softwoods are gymnosperm, which are plants that let the seeds fall to the ground with no covering (What is the...

Shortleaf pine tends to grow rather slowly in the early stages of its life when compared to its closest competitor, loblolly pine. Therefore it cannot compete for the best sites under natural regeneration, but, because of it's tolerance of a wide range of site conditions, shortleaf pine is found naturally in areas where loblolly pine will not grow effectively. It is for this reason that shortleaf pine was chosen for this site instead of loblolly. When planted artificially, it was found that after the first few years of development, shortleaf pine will match loblolly in height growth on the better sites and will surpass loblolly on the poorer sites (Harrington, 1987). Because of this, shortleaf pine is the most commonly regenerated pine in the northern and western parts of its range where the site conditions are not as ideal as in the southern part of its range.
For the first phenomena, he noted how all combustions involved the formation of fire or light. With that in mind, Lavoisier also observed that this combustion occurs only through dephlogisticated air / pure air. Other airs (e.g. carbon dioxide) act as a fire extinguisher similar to that of water. Another combustion phenomenon he outlined was how the weight of the burnt material directly relates to the amount of air used in the reaction. Moreover, he also described how certain substances turn into acids after it has been burn...
With the 10:00 a.m. policy any fire that breaks out was to be under control by 10:00 a.m. the following day. This policy was based on the theories about forest management in the plantation forests of Europe. But ecologists have later discovered that burning is essential for the preservation of many natural forest communities. For example the cone of the jack pine and the lodgepile pine will not release seeds unless they are exposed to the intense heat of a forest fire. Fire also helps animals by allowing new vegetation to grow on the cleared soil.
Although fire is linked to human life, as it is essential for survival, not only its use for food, security and warmth, particularly in the extreme cold weather
Combustion is a rapid, continuous reaction that usually takes place in the gas phase. Wood is an organic compound primarily comprised of cellulose. For wood, the phase change from a solid to gas is almost instantaneous as combustion occurs (Coleman, et al. 95). Ignition occurs when an outside source is no longer needed to sustain combustion (Coleman, et al. 87).
There are three types. of heat: conduction, convection and radiation. There are a number of ways to control the heat lost, an example is taking tiles and. surrounding the fire to decrease the area of the heat that can be lost. so more heat is trapped in the water.

Words have so many different meanings. Just pick up a dictionary to discover the many different meanings of the same word. Have you ever wondered where the meaning of the word originated? Maybe you have asked what a word means when another has used it out of context. How did one word come to mean so many different things? This paper will allow me to explore the definition of burn and where it originated. I will also discover how it has changed over the years and what the definition is today.

This container must have a value of specific heat capacity so I can calculate heat transferred to it as well. Probably the most conductive container available for use in the classroom is a calorimeter. As well as not wasting energy on the heating of the container, I could also try to stop heat from escaping the top and edges of the container by covering it with a fitting lid. I will try to prevent the wind from blowing the flames in a different direction so all the windows must be shut. HYPOTHESIS More energy is released as more bonds are formed, below is the list of approximate energy required to break and form all bonds involved in burning alcohols.
We scurried to the garage, carrying paper and other “burnables.” Matches were always better than lighters for experiments such as these. For our first experiment, we ignited napkins and paper, but the excitement quickly fizzled. Having lost our initial adrenalin rush, we began to search for more dangerous “flammables.
Full combustion should generate two products only: carbon dioxide and water vapour. Hypothesis Within a molecule there are bond energies that hold the atoms together. When the fuel combusts, a chemical reaction takes place, this breaks the bonds, this requires energy, and makes new bonds, this gives out energy. The energy differences between the two tell us how much energy was given out or taken in. We can show this in a graph.

There are different classes of fire and extinguishers which depends on what is on fire. This is important to familiarize with to be able to know what type of extinguisher should be used in case of fire.
The different colors of the flames can indicate things such as temperature and use of accelerants. The bun patterns left by flames can indicate the point of origin and how fast the flames spread. Investigators can see how long the fire was burning and when it was put out. Flames and smoke can show if the fire was accidental or if it was
