Calorimetry
The experimental science and practice of measuring heat energy changes during chemical or physical transformations.
Governing formula
Q_lost = Q_gained ⇒ m1 c1 (T1 - T_f) = m2 c2 (T_f - T2)
SI unit
J
In depth
Relies on conservation of energy within insulated vessels called calorimeters to determine specific heat capacities or reaction enthalpy.
Examples in the real world
Using a bomb calorimeter to measure caloric energy content in food samples by complete combustion.
