Book Chapter
Information on explosions from a section of the book "Energy" is presented. It explains that explosion is a process in which two or more chemicals react together to make a large blast of fast-moving gas. It notes that the energy of explosions can be useful or entertaining when harnessed properly. The four kinds of kinetic energy involved in lighting a firework are light, heat, sound and motion. The explosion of an air bag when a car crashes leads to the generation of a huge cloud of nitrogen gas moving at 320 kilometers per hour.
