Calorimetry measures heat flow in physical or chemical processes using instruments called calorimeters. By measuring temperature changes in a known mass of water (or other medium), scientists determine reaction enthalpy (ΔH) or heat capacity. Common techniques include constant-pressure calorimetry (coffee cup calorimeter) and constant-volume calorimetry (bomb calorimeter). Calorimetry is essential in nutritional science (food calorie measurement) and industrial process design.
