Abstract
Energy content or calorific value is the same as the heat of combustion, and can be calculated from thermodynamical values, or measured in a suitable apparatus. A known amount of the fuel is burned at constant pressure and under standard conditions (0°C and 1 bar) and the heat released is captured in a known mass of water in a calorimeter. Mar 28, 2013 Paraffin wax has a density of roughly 0.8 gm/cm3. It will float in any fluid whose density is greater than roughly 0.8 gm/cm3. What country does paraffin wax come from? Paraffin wax is produced. The surface energy values of some typical materials are shown in the two tables. The first table shows values for low and high surface energy solid materials, whilst the second table shows values for the liquids used in contact angle measurements that are used to determine surface energies. Density: 1.858 g/cm 3: Melting point: 205.5 °C (401.9 °F; 478.6 K) Boiling point: 234 °C (453 °F; 507 K).
TheMethods/Materials
In my experiment I used a home-made calorimeter to measure the energy of combustion for paraffin wax, gasoline, vegetable oil, diesel, sterno, and wood. A calorimeter is a device used to determine the amount of energy given off during a chemical reaction by measuring the change in temperature of water surrounding a reaction crucible. I recorded the starting temperature of the water and the mass of the fuel that I placed in the calorimeter. The fuel was lit and oxygen was circulated through the container. I sealed the crucible and placed it into a large bucket of water. After twenty minutes I stopped the experiment and measured the change in temperature of the water and the change in mass of the fuel. With this information I calculated the total energy released and the energy density of each fuel.
Results
My experiment showed that paraffin wax had the greatest energy density of the six fuels I tested, while wood had the lowest energy density.
Conclusions/Discussion
My conclusion did not support my hypothesis, although gasoline did have the second greatest energy density. This experiment shows that there is a significant difference between various fuels and suggests that in the future wax may become a more vital source of energy.
This project is about a calorimeter to determine the energy densities of six different fuels.
