In this video, I explain why some reactions explode while others cool, exploring the root cause of chemical energy. I discuss ...

Students explore the concept that chemical reactions involve the breaking of bonds between atoms in the reactants, and the rearrangement and rebonding of these atoms to make the products. Students ...

Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes. In Chapter 5, students learned how the process of dissolving ...
