Fuels and energetics

This unit examines energy changes in state, exothermic and endothermic reactions, and energy transfers in various processes. It emphasises objectivity, accuracy, and precision in scientific enquiries, data interpretation, and the use of tables, graphs, and reliable methods.

Prior knowledge

  • In a chemical reaction, atoms rearrange themselves to form new substances
  • Chemical reactions cannot usually be reversed easily
  • Combustion is the reaction of substances with oxygen
  • Burning is also used to describe the reaction of substances with oxygen, but is most often used when flames are seen
  • Combustion requires three things: fuel, heat and oxygen

Source curriculum references

  • Pay attention to objectivity and concern for accuracy, precision, repeatability and reproducibility
  • Select, plan and carry out the most appropriate types of scientific enquiries to test predictions, including identifying independent, dependent and control variables
  • Make and record observations and measurements using a range of methods for different investigations; and evaluate the reliability of methods and suggest possible improvements
  • Present observations and data using appropriate methods, including tables and graphs
  • Interpret observations and data, including identifying patterns and using observations, measurements and data to draw conclusions
  • Present reasoned explanations, including explaining data in relation to predictions and hypotheses
  • Energy changes on changes of state (qualitative)
  • Exothermic and endothermic chemical reactions (qualitative)
  • Fuels and energy resources
  • Other processes that involve energy transfer: changing motion, dropping an object, completing an electrical circuit, stretching a spring, metabolism of food, burning fuels
