Energy Content of Fuels

Figure from experiment 24 from Agricultural Science with Vernier

Introduction

Energy content is an important property of fuels. This property helps scientists and engineers determine the usefulness of a fuel. Energy content is the amount of heat produced by the burning of 1 gram of a substance, and is measured in joules per gram (J/g).

You can determine energy content of a fuel by burning an amount of the fuel and capturing the heat released in a known mass of water in a calorimeter. If you measure the initial and final temperatures, the energy released can be calculated using the equation

H = \Delta t \cdot m \cdot C_p

where H = heat energy absorbed (in J), Δt = change in temperature (in °C), m = mass (in g), and Cp = specific heat capacity (4.18 J/g°C for water). Dividing the resulting energy value by grams of food burned gives the energy content (in J/g).

Objectives

In this experiment, you will

  • Measure temperature.
  • Analyze data.
  • Use a balance.
  • Determine energy content.
  • Compare the energy content of different fuels.
