Endothermic (and exothermic) analysis only accounts for the enthalpy change (∆H) of a reaction. Source: Internet
Care must also be taken to avoid freezing or overheating due to the exothermic setting of cement. Source: Internet
A relatively easy way to determine whether or not a reaction is exothermic or endothermic is to determine the sign of ΔH. Source: Internet
A steady stream of oxygen gas is then produced by the exothermic reaction. Source: Internet
Dust explosions Pyrite oxidation is sufficiently exothermic that underground coal mines in high-sulfur coal seams have occasionally had serious problems with spontaneous combustion in the mined-out areas of the mine. Source: Internet
