Chemical Reactions That Cause Cooling . The removal of heat from exothermic processes is very important for process control and safety reasons, and cooling may also be required to create the right conditions for certain process steps. 238000006243 chemical reaction methods 0.000 title description 120; Ordinary Portland Cement Tests, Properties, Manufacture & Uses from www.aboutcivil.org Warm air from the outside is collected and funneled toward a solid. Thus, air coolers work on the principle of cooling effect caused by evaporation. Examples for evaporation causes cooling are:
