  1. Revolution and Order(1770-1815) CM1100 History of Chemistry: Gases and the Gas Laws

  2. The Genesis of Fire • “And God said: Let there be Fire” (The Ancient Greek word, Phao, means both Light and Fire) • Building on Aristotle’s belief, Fire was regarded as one of the 4 key elements of alchemy • To alchemists Fire represented purification and change • Because of this key role many studies on the nature of Fire were performed in the 17th and 18th century

  3. Flox and Phlogiston • In the early 18th century, Becher suggested that a hypothetical substance, called "inflammable earth“, was contained in every flammable material. It was released in the process of burning leaving the “pure” material (calx) • The released “substance” was later called “PHLOGISTON" (from the Gk word FLOX meaning “flame of fire”) by Stahl
