2.33B: Practical: Investigate the Energy Content in a Food Sample

INVESTIGATING ENERGY CONTENT IN FOOD SAMPLE
Diagram showing Investigation of Energy Content in Food Sample via Combustion
METHOD:

  • Measure a fixed volume of Water into a boiling tube
  • Use a thermometer to measure the temperature of Water
  • Use a weighing scale to measure the mass of food sample
  • Burn food sample via complete combustion and hold directly underneath the boiling tube to heat the Water until it burns out
  • Use thermometer to measure the final temperature of Water

EQUATION:

Equation to calculate Energy Transferred to Water is (Energy content in Food):
