Going Green, Fuel Style!! The Test of Alcohol & Lamp Oil Tagen Bryant, Ernest McDonald, Lauren Reed, Eric Wickliffe
Introduction Gas prices on rise Average: $4.10 Gasoline is infecting the environment
By testing the energy output of denatured alcohol and lamp oil, we are able to tell which form of fuel is the better buy. However, we need to find a fuel that will not hinder the environment. In this test we were also able to watch the fuels burn and see which fuel burned cleaner. Both fuels that are being tested are lower & safer forms of the ethanol and petroleum gas. Purpose
Hypothesis If we burn each fuel for 7 minutes then, the alcohol will burn cleaner, but produce less thermal output and lamp oil will burn dirtier, but produce more thermal output.
Denatured Alcohol Uses: To kill insects In mouthwash For camp stoves To remove excess dust from sanding wood Advantages: Low cost, its ability to be extinguished by water, and its easier to transport Disadvantages: Hazardous because the flames are invisible.
Lamp Oil Uses: Emergency indoor lighting Mood Lighting Alternative to candles Advantages: None Disadvantages: More expensive than denatured alcohol
Materials 1L Hydrocarbon 1L Biofuel 1 Thermometer 1 Stopwatch Water (in excess) Ice 1 Alcohol Burner 1 Erlin Meyer Flask 1 Stand 1 Clamp 1 Coffee Can (calorimeter)
Procedure 1.Cool 125mL water to 17 ⁰ C. 2.Set up stand and clamp on flat surface. 3.Put 200mL degenerated alcohol into alcohol burner and place under stand. 4.Put chilled water and calorimeter can on stand above alcohol burner. 5.Take initial temperature of water and weight of burner. 6.Light burner and begin stopwatch.
Procedure Cont’d 7. Heat water for 7 minutes. 8. Take temperature of water immediately after 7 minutes. 9. Take weight of alcohol burner recording all data and observations. 10. Repeat steps 4 through 9 for At least 2 more trials. 11. Repeat steps 3 through 9, replacing alcohol with hydrocarbon in step 3, and its trials. 12. Calculate the thermal output in calories per grams used
Results Cont’d Average Alcohol – cal/g HC Fuel – cal/g
Conclusion Our hypothesis was proven correct. Things that could have been done if we had more time and resources: Use ethanol and petroleum gas Mix two fuels to see if thermal output is higher or lower than the other two.
