Phlogiston and Oxygen

The video explores the transition from the flogiston theory to modern chemistry. It begins with Priestley's discovery, which lacked significance until Lavoisier's precise experiments. Lavoisier's work debunked the flogiston theory by demonstrating that substances gain mass when heated, leading to the discovery of oxygen. This marked a turning point in chemistry, establishing the modern concept of chemical elements and earning Lavoisier the title of the father of modern chemistry.

What conclusion did Lavoisier reach regarding the gas involved in combustion?

What was the significance of Lavoisier's work at the end of the 18th century?
