Melting water endothermic or exothermic
Web26 sep. 2024 · Is Melting Endothermic Or Exothermic When it comes to melting, there is a bit of confusion about whether the process is endothermic or exothermic. The answer actually depends on the material that is melting. For example, when ice melts, the process is exothermic because heat is released. Web23 feb. 2024 · To investigate the influence of the CFA type, an exothermic and an endothermic CFA were selected. The exothermic CFA used is a polymer-bound modified azodicarbonamide (Tracel IM 3170 MS) from Tramaco, Germany, with a reported decomposition temperature of about 170 °C. During the reaction, it releases heat and …
