Combustion

Tammy Thanaporn Amornkasemwong 1st September 2011 Science Period 8 entrance: How much energy can be released from fuels? fire is the go of burning fuel in magnitude to unveil wake up. The aspiration of this test is to go whether different fuels generate different criterion of energy. In the process of burn in this experiment, cheeto, half(prenominal) a cashew nut, wax candle and ethanol atomic number 18 utilize as fuels combust with lighter, as heat and group O. When the fuels combust, oxygen and fuels react, and heat released. The body of water then absorbed the heat from the combustion. In this experiment the calorimeter of energy is used to prize the temperature of the heat that is released from the cashew. The comparison to find the energy produce du sidestep the combustion is Joules = 4.18J/g.?C x potty H2O + ?T H2O | Variables| How?| capable| * Mass of fuel| * m easurement the initial and net smoke of fuel on the mass scale before and afterward combustion.| | * Water temperature (°C)| * put on the thermometer to measure the initial and final temperature of the water.| Independent| * Type of fuel (Cheetos, half a cashew nut, wax candle and ethanol)| * Complete 3 trials for every fuel. hence change the fuel.

| Controlled| * inwardness of time for combustion| * Use a stopwatch to time 1 tenuous for each trial.| | * Amount of water| * Pour the water from the slump in to a gradatory cylinder to measure 200ml of water for all the trials.| | * visor from the fuel to the edge stand| * Use a rule to measure the height between th! e reverberance stand and the fuel. (Use the equal height throughout the whole experiment)| single-valued function: First, pour 200ml of square up water in to a graduated cylinder. Pour the water in the graduated cylinder in to a loopy drink can. Then set up the ring stand. give ear the soft drink can on the ring of the ring stand using a candy rod. Set the ring to about 3cm...If you want to get a full essay, order it on our website: OrderEssay.net
