Fuels and Their Efficiency to Produce Energy

CSEF · 2005 Chemistry

Brent M. Yamada · Canyon Middle School, Yucaipa

Overview

Objectives/Goals My project was to evaluate and test four different fuels - parrafin wax, ethanol, propane, and white gas (similar to gasoline) - to determine which is most efficientin producing heat and energy. Methods/Materials Four different fuels were used to heat water in a flask. By measuring the temperature change, and the amount of fuel burned, I calculated the amount of energy produced in kilojoules/gram. Using mathematical sequences, I calculated the heat of combustion and their efficiency in producing energy for all four fuels. Results Parrafin wax had the highest heat of combustion and efficiency, followed by ethanol, then propane, and white gas finished last. Conclusions/Discussion I conclude from my results that parrafin wax was the most efficient of all four fuels. Because of its efficiency, its clean burning properties, andits safety in storage, it could have more widespread applicates in the future.

Summary statement

Four common fuels (parrafin wax, ethanol, propane, & white gas) were burned to determine their efficiency in producing energy and parrafin wax was the most efficient.

Help received

My parents purchased all necessary lab equipment, office supplies, and took me to the library.
