Two dry solids --- barium hydroxide and ammonium nitrate --- are mixed to produce an endothermic reaction. The temperature of the mixture drops approximately 45oC and is cold enough to freeze the ...

Science presenter Jon Chase demonstrates an exothermic and an endothermic reaction, and explains how temperature changes can be used to identify which reaction is which. The exothermic reaction is ...

This video is about what exothermic and endothermic reactions are and how temperature changes can be used to identify which reaction is which. Exothermic reactions, in solution, give out energy ...
