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...

- James Kelman's story, The Burn has been interpreted as a universal representation of the condition of the working class in an oppressive society. Also, critics have brought to light the stylistic accomplishment of Kelman's writing; his ability to use language to bring to bear a psychological and emotional state of being within a fraction of an individual’s life; but, there is another perspective that may have been an unintentional result of his genius as a writer. His unnamed character gives us an additional lens to view his journey.... [tags: The Burn Essays]

- Analysis of Burn's Poem A Red, Red Rose 'A Red, Red Rose', was first published in 1794 in A Selection of Scots Songs, edited by Peter Urbani. Written in ballad stanzas, the verse - read today as a poem – pieces together conventional ideas and images of love in a way that transcends the "low" or non-literary sources from which the poem is drawn. In it, the speaker compares his love first with a blooming rose in spring and then with a melody "sweetly play'd in tune." If these similes seem the typical fodder for love-song lyricists, the second and third stanzas introduce the subtler and more complex implications of time.... [tags: Burn Red Red Rose Essays]
