Is freezing ice exothermic
WebWhy is freezing ice exothermic? When water becomes a solid, it releases heat, warming up its surroundings. This makes freezing an exothermic reaction. Why is ice melting called an endothermic process and not an endothermic reaction? Explanation: Water is a higher energy state, as the liquid can rotate and vibrate while solid ice can only vibrate. WebLead a discussion on some common exothermic and endothermic reactions. Elicit examples from students and provide additional examples. Examples include: Mixture of cement and water (exothermic) Melting and freezing of ice (endothermic and exothermic) Baking soda and water (exothermic) Hot packs and cold packs (endothermic, endothermic)
