Questions and Answers

Which of the following factors does NOT influence the rate at which a fuel releases energy over time?

  • Chemical composition
  • Kinetic energy (correct)
  • Density of the fuel
  • Arrangement

In the context of fuel combustion, why is the availability of oxygen crucial?

  • To accelerate the arrangement of molecules in the fuel
  • To reduce the density of the fuel
  • To increase the chemical composition of the fuel
  • For the combustion process to release energy effectively (correct)

How does the arrangement of a fuel's molecules affect its energy release rate?

  • It increases the availability of oxygen for combustion
  • It accelerates the combustion process
  • It decreases the density of the fuel
  • It determines how efficiently energy is released during combustion (correct)
