smog | National Geographic Society

Smog is air pollution that reduces visibility.The term "smog" was first used in the early 1900s to describe a mix of smoke and fog.The smoke usually came from burning coal. Smog was common in industrial areas, and remains a familiar sight in cities today. Today, most of the smog we see is photochemical smog. Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least ...

4.1 Energy and Metabolism - Concepts of Biology - 1st Canadian Edition

An important concept in physical systems is that of order and disorder. The more energy that is lost by a system to its surroundings, the less ordered and more random the system is. Scientists refer to the measure of randomness or disorder within a system as entropy. High entropy means high disorder and low energy.
