Combustion

In this lab, we tested different experiments on a candle flame in order to better understand properties, combustion, and states of matter. We recorded many observations that could help us reach a conclusion using what we saw happen. When we observed the regular candle flame, we concluded that the heat of the flame vaporizes the liquid wax. Then, we blew this candle out and took a different lit candle into the smoke trail from the burnt out candle. The wax vapor in the smoke is combustible,…

To begin with, a basic part of human civilization and life is the element of fire, though a fire is not all that basic. A fire is not a simple element, but it is a complex part of chemistry that requires multiple elements. First of all, a fire starts due to a hot temperature igniting the combustible material. Most of the common material found lying around can burn but only if there is a high temperature to ignite the material; the minimum required temperature to burn an object is known as the…

My experiment is about which type of paper will burn the longest. Fire is a compound that is used in a lot of ways all around the world for burning objects or heating them, it also causes chemical changes. I chose this experiment because I wanted to learn more about fire, more specifically, I wanted to learned how it functioned. I was interested to learn how fire functioned and how it maintained itself. “What did it depend on? What kept it going,” these were question that I’ve kept in mind…

Introduction Fire investigation includes the scrutiny of every fire-related incident once the fire is extinguished by the firefighters. The practice of fire scene examination is related to the inspection of a crime scene and like any other crime scene, the fire scene must also be preserved and the evidences are collected and analyzed; however, it involves several additional dangers and difficulties. The investigation will include close survey of the damaged scene in order to establish the source…

and help current industries become what they are today. Although many sources of energy have been discovered by the U.S., they have chosen the use of fossil fuels as their main source of energy. Fossil fuels have been used to provide power for combustion engines,…

Combustion is a chemical reaction between substances, according to www.scienceterms.com, "[Combustions processes] usually including oxygen and usually accompanied by the generation of heat and light in the form of flame. The rate or speed at which the reactants combine is high, in part because of the nature of the chemical reaction itself and in part because more energy is generated than can escape into the surrounding medium, with the result that the temperature of the reactants is raised to…

Name: Ben Tanke, Brooke Binkley, and Hailey Fenn Block: 3rd Title: Gunpowder QPOEE Question: Which amount of Sulfur(.25 grams, .5 grams, .75 grams, and 1 gram) creates the closest reaction with fire as the store bought gunpowder in terms of size of flame and the time duration of the flame? Knowledge Probe: The equation for the reaction of our gunpowder is 10Na NO3 + 8C + 3S → 2 Na2 CO3 + 3Na2SO4 + 6CO2 + 5N2. This shows that Sodium Nitrate is reacting with…

A study was conducted to test the efficiency of the TPS created, by changing the size of the flame. The flame sizes tested were 3 cm, 5cm, and 7cm. It was predicted that if the flame was bigger, then the screw would fall out quicker because there was more of the flame exposed to the TPS, causing it to deteriorate quicker. It was found that 5 cm flame caused the least amount of damage to the TPS. It showed that the TPS was very effective, because the screw stayed attached to the wooden dowel for…

To start off my hypothesis is, if a lighter colored candle has more entrapped air then it will burn quicker because they have less wax. I got this idea from engineering.com and my mom. I thought that this experiment would be fun because if I could prove it was correct then darker color candle would be a better option to buy because they will last longer. Next, the purpose of this experiment is to show if color affects the amount of time a candle burns. Going back to what I said in the paragraph…

Today i’m going to tell how you to properly start and stop an oxyacetylene cutting torch. An oxyacetylene cutting torch is a device used to cut through metal, and uses both Oxygen and Acetylene. They can produce a very large amount of heat. First off, anytime you use the torch in the shop you must always wear your personal safety equipment, such as a long sleeve shirt, pants, boots, safety glasses, and gloves. If you’re not real sure on what you need to wear, ask your teacher. You must…
