Introduction:
When chemical reactions occur gases can be released. The laws governing the interaction of pressure, volume, and temperature, allow us to predict what will happen with those gases. Since most of you seem to enjoy watching things blow up, this unit should prove interesting and provocative. Gases that are quickly released form the basis for many explosions. Knowing how pressure, temperature, and volume interact can help you understand what outcome will be achieved by mixing certain chemicals together. Of course, ultimately, it would be helpful to know a little physics too.
