“The exothermic reaction between hydrogen and oxygen produced a significant amount of heat energy.”

“The reaction of some hydrocarbons with iron ores is exothermic, so that additional heat may not be required.”

“For these exothermic processes, the solubility decreases with an increase in temperature.”

“One may see from the Figure that in the process of heating exothermal phase transformations occur in the foils.”

“The process took advantage of the exothermal effect of reactions.”

“Since some of the projects are exothermal reaction and some are endothermal, a total of 200,000 tons of standard coal can be saved through internal heat conversion.”
