The Calorimetry Calculator calculates the amount of heat energy transferred during a process using the formula q = m × c × ΔT, where m is the mass of the substance, c is its specific heat capacity, and ΔT is the change in temperature. This tool helps analyze whether a reaction or process is endothermic (absorbs heat) or exothermic (releases heat), providing results in both joules (J) and kilojoules (kJ).
