🔥Enthalpy Change Calculator (Q=mcΔT)
Water=4.18
Enthalpy (H) is a thermodynamic property measuring the total heat content of a system at constant pressure. Enthalpy change ΔH = q = m × c × ΔT for calorimetry calculations. Exothermic reactions release heat (ΔH < 0); endothermic absorb heat (ΔH > 0).

Fun Fact
The standard enthalpy of combustion of octane (petrol) is −5,471 kJ/mol. One litre of petrol stores about 34,000 kJ of chemical energy — enough to heat a bathtub of water by 50°C.
