Abstract: The aim of this experiment was to investigate the relationship between the types of biodiesel, the energy (kJ) it contained per 100mL and the energy produced from the combustion of the biodiesel (kilojoules per gram). The results show that there was a relationship between the energy contained (kJ/100 mL) and the energy given off (kJ/g). This relationship was a linear relationship. It was linear as the amount of energy within the vegetable oils (100mL) should be proportional to the amount of kilojoules per gram given off.
Introduction:
In society today, the main source of energy for vehicles worldwide is fuels such as diesel and petrol. These resources are becoming scarcer as people continue to use this resource on a daily basses. Not only is this resource running out but it is also polluting the environment surrounding. The answer to these problems is to use another resource that is both good for the environment and available in large quantities, this other resource is biodiesel. Biodiesel is a fuel which was used and distributed during the 1920’s, 1930’s and even during World War 2. Although fuels like diesel and petrol were available, the interest of vegetable oils grew as it was both economical and available in excessive amounts.
When the diesel engine was invented in early 1900’s by Rudolph Diesel he made it to be powered by vegetable oil. This was the first case when biodiesel was encouraged as those engines were designed to withstand the chemical aspects of Biodiesel. “Biodiesel is produced from renewable plant or animal feedstock’s containing fatty acids using a process of condensation called transesterification, and are the most common form of biofuel in Europe as a replacement for diesel.” (Biofuels Association of Australia , 2014). Ever since Rudolph designed such an engine (To be compatible with biodiesel), The world was able to build on his idea and design new and better engines which will use the Biodiesel more efficiently.
In the diagram below (Diagram 1) of a Calorimeter, it shows what is used and how it is setup. The idea of this design is to contain all the heat and aim it towards the water in order to gather more accurate results. However the diagram below (Diagram 1) is a setup which is used for finding the amount of energy within food not the energy that was given off for Biodiesel. It measures heat or energy gained (endothermic) or lost (exothermic) in a reaction, which in this case is Biodiesel. The heat that will be given off by the combustion reaction (burning biodiesel) will equal heat gained by water in calorimeter. The Formula that will be used to measure the amount of energy within each biodiesel is q=mCΔT. This formula is a general formula which can be used to determine the amount of energy within a substance. q is the energy which is trying to be found. M is the mass of the given substance in
