During the mid-eighteenth century, the discovery of the steam engine, which converts the chemical energy latent in fuels to mechanical energy, ushered in the Industrial Revolution. Today fuels not only heat our homes and move our cars but are necessary for every facet of modern technology.   For example, fuels generate the electricity required for our modern computing and communications technologies, and they propel the rocket engines that make possible our explorations of outer space.   Foods as Fuels The body generates energy from food by the same overall process as combustion, so the overall enthalpy change is the same as the heat of combustion, which can be determined in a calorimeter. You can get some idea of the energy available from carbohydrate foods by looking at a typical one, glucose (C6H12O6). The thermoch...

Your aim is loftier when you talk to yourself in words. But your happy chemicals respond to improvements in your survival prospects, however, you’ve learned to define them. A student gets a surge of dopamine when he sees the highest results on his result sheet. A gamer is fueled by dopamine as he wins his game. “I did it!” the brain tells the body.
