In our everyday experience, energy seems to disappear all the time. Batteries go dead, a wind-up toy stops moving, fires run out of fuel. But the reality is that energy is never destroyed, it only changes from one form to another. In this section we present a number of examples of how energy transfers account for where energy goes in chemical and physical reactions. We also present a career profile of a chemist who works for an energy company.
