Explain how the temperature of the metal and the water bath become equalized, and how that final equalized temperature is measured. 2. Heat loss causes a lower T f. Examine Figure 25.5 and read the label over the line to see the overall effect on T f If you measure the initial and final temperatures, the energy released can be calculated using the equation Q = Δt*m*c, where Q = heat energy absorbed (in J), Δt = change in temperature (in °C), m = mass (in g), and c= specific heat capacity (4.185 J/g°C for water). Q/g of food burned gives the energy content per gram. Lesson Files.
