3.12: Energy and Heat Capacity Calculations
Solution. The question gives us the heat, the final and initial temperatures, and the mass of the sample. The value of ΔT is as follows:. ΔT = T final − T initial = 22.0°C − 97.5°C = −75.5°C. If the sample gives off 71.7 cal, it loses energy (as heat), so the value of heat is written as a negative number, −71.7 cal. Substitute the known values into heat = mcΔT
