Learning Objectives

• calculations related to the application of stoichiometry to reactions involving the combustion of fuels, including mass-mass, mass-volume and volume-volume stoichiometry, to determine heat energy released, reactant and product amounts and net volume or mass of major greenhouse gases (CO₂, CH₄ and H₂O), limited to standard laboratory conditions (SLC) at 25 °C and 100 kPa

• the use of specific heat capacity of water to approximate the quantity of heat energy released during the combustion of a known mass of fuel and food

• the principles of solution calorimetry, including determination of calibration factor and consideration of the effects of heat loss; analysis of temperature-time graphs obtained from solution calorimetry

• energy from fuels and food:

  • • calculation of energy transformation efficiency during combustion as a percentage of chemical energy converted to useful energy 

    • comparison and calculations of energy values of foods containing carbohydrates, proteins and fats and oils
