How did Lavoisier see things differently from Aristotle?

What did Lavoisier find out about air from his experiments?

In experiments with phosphorus and sulfur, both of which burned readily, Lavoisier showed that they gained weight by combining with air. With lead calx, he was able to capture a large amount of air that was liberated when the calx was heated. … He eventually concluded that common air was not a simple substance.

Who is the mother of chemistry?

What does a Calx being heavier than its metal show?

Solving the Riddle of Rust Lavoisier found that a calx of lead, mixed with charcoal and heated by the sun’s rays, gave off a large amount of air as it turned back into metallic lead. This suggested that air, or some part of the air, might somehow responsible for calxes’ being heavier than expected.

The combination of lecture plus lab can be intimidating.

What was Lavoisier’s theory?

Lavoisier hypothesized that it was probably the fixation and release of air, rather than fire, that caused the observed gains and losses in weight. This idea set the course of his research for the next decade. Along the way, he encountered related phenomena that had to be explained.
