Energy Density = Energy × Volume-1. (1) Since, Energy = Force × d = m × a × d. Therefore, the dimensions of energy = M 1 L 2 T-2. (2) And, the dimensional formula of volume = M 0 L 3 T 0. (3) On substituting equation (2) and (3) in equation (1) we get, Energy Density = Energy × Volume-1 = M 1 L 2 T-2 × M 0 L 3 T.

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.
Abstract
The objective: The purpose of my project was to determine which fuel had the greatest energy density. I hypothesized that gasoline would have the greatest energy density because it is used commonly in many forms of transportation.
Methods/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.
Energy Density Of Wax Paper
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.
