Experiments
Here are experiments our science specialists have selected to support this IB* topic.
Fossil Fuels
Experiment #26 from Investigating Environmental Science through Inquiry
In the Preliminary Activity, you will determine the heat of combustion of paraffin wax (in kJ/g). You will first use the energy from burning paraffin wax to heat a known quantity of water. By monitoring the temperature of the water, you can find the amount of heat transferred to it (in kJ), using the formula
where q is heat, Cp is the specific heat capacity of water, m is the mass of water, and Δt is the change in temperature of the water. Finally, the amount of fuel burned will be taken into account by calculating the heat per gram of paraffin wax consumed in the combustion.
After completing the Preliminary Activity, you will first use reference sources to find out more about fossil fuel energy before you choose and investigate a researchable question.
