Chemistry. Unit 7, The energy in chemical reactions : thermodynamics and enthalpy / [produced by the Science Media Group at the Harvard-Smithsonian Center for Astrophysics]
The phrase "chemical reaction" conjures up images of explosions, bubbling gases, flames, and smoke. So many chemical reactions have visible results because energy is being transferred from one form to another -- the realm of thermodynamics. Thermodynamics provides rules for predicting the progress of a reaction and for harnessing the energy released. It is key to solving pressing engineering problems, such as making the next generation of cleaner, and more efficient, automobile engines
