Chemistry design: Fuel energy lab Research question: What is the energy density of cyclohexane‚ and how does it compare to the energy density of normal hexane? Variables: Independent variable – The independent variable in this experiment will be the type of fuel that will be used. This will be either Hexane or Cyclohexane. Each type will be given to us and labelled so it will be quite simple to control this variable. This cannot be measured using any apparatus so the lab assistant must be entrusted
