Exothermic event

WebThis is exothermic in nature. See, basically what happens, when we throw off unused vegetables or fruits, bacteria and fungi, they all act on it and they decompose it, they break it down. Now in this process, a lot of energy's being released, and that's why this is an exothermic process. WebOct 9, 2012 · Once the exothermic initiation occurred, in duration of less than 100 min, the temperature rose to 300 °C. Although the onset temperature (120 °C) for the mixture with 30 % water content was higher, the behavior of the exothermic event was similar to that of the mixture with 40 % water content; but with a higher end point i.e., 340 °C.
