Which statement below would be accurate about boiling water? Boiling water is an exothermic process and to break apart the intermolecular forces that hold together the water molecules requires +40.7 kJ of energy. Boiling water is an endothermic process and to break apart the intermolecular forces that hold together the water molecules release 40.7 kJ of energy. Boiling water is an endothermic process and to break apart the intermolecular forces that hold together the water molecules requires +40.7 kJ of energy.
