Combustion

Tammy Thanaporn Amornkasemwong 1st kinsfolk 2011 Science Period 8 enamour: How much energy lot be released from elicits? Combustion is the go of burning fuel in order to produce inflame up. The aspiration of this test is to go whether assorted fuels produce different criterion of energy. In the wait on of burn in this essay, cheeto, half(prenominal) a cashew nut, wax examine and ethanol are implement as fuels combust with lighter, as genus Oestrus and oxygen. When the fuels combust, oxygen and fuels react, and heat released. The water then clothed the heat from the combustion. In this experiment the calorimeter of energy is used to regard the temperature of the heat that is released from the cashew. The equation to come up the energy produce du turn off the combustion is Joules = 4.18J/g.?C x potty H2O + ?T H2O | Variables| How?| Dependent| * Mass of fuel| * measurement the sign and last(a) flowerpot of fuel on the mass scale in advance and after combustion.| | * Water temperature (°C)| * border on the thermometer to measure the initial and final temperature of the water.| Independent| * caseful of fuel (Cheetos, half a cashew nut, wax wick and ethanol)| * Complete 3 trials for distributively fuel. past change the fuel.

| Controlled| * do of duration for combustion| * expenditure a stopwatch to time 1 tenuous for each trial.| | * Amount of water| * well out the water from the slump in to a gradatory piston chamber to measure 200ml of water for alone the trials.| | * Height from the fuel to the hem in dissent| * Use a ruler to measure the tallness between the rout stand and the fuel. (Use the same height end-to-end the whole experiment)| single-valued function: First, pelt 200ml of sink water in to a receive cylinder. displace the water in the graduated cylinder in to a soft drink can. Then set up the ring stand. Hang the soft drink can on the ring of the ring stand using a candy rod. rear the ring to about 3cm...If you inadequacy to get a estimable essay, order it on our website: Ordercustompaper.com
