What is an interesting fact about Joseph Priestley?
Joseph Priestley FRS (March 24, 1733 to February 6, 1804) was an English theologian, natural philosopher, chemist, teacher and Liberal political theorist. He is best known for isolating Oxygen in its gaseous state. He also invented soda water.
Did Joseph Priestley discover photosynthesis?
Several centuries later, Joseph Priestley (1733 – 1804) carried out an experiment that showed that plants produce oxygen. He put a mint plant in a closed container with a burning candle. After 27 days, Priestley was able to re-light the candle. This showed that plants produce a gas that allows fuels to burn.
What did Joseph Priestley discover about the atom?
The discovery of oxygen and the chemical revolution of Joseph Priestley. Priestley’s lasting reputation in science is founded upon the discovery he made on August 1, 1774, when he obtained a colourless gas by heating red mercuric oxide.
Who discovered the process of photosynthesis?
Jan Ingenhousz
Dutch-born British physician and scientist Jan Ingenhousz is best known for the discovery of the process of photosynthesis, by which green plants in sunlight absorb carbon dioxide and release oxygen.

When did Joseph Priestley come up with the idea of photosynthesis?
Experiment by Joseph Priestley In 1770, after a series of experiments, Joseph Priestley came to a conclusion regarding the essentiality of air for photosynthesis and also for the growth of plants. Materials required: A bell jar, candle, rat, and a plant.
Why was Joseph Priestley important to the scientific community?
Priestley’s determination to defend phlogiston theory and to reject what would become the chemical revolution eventually left him isolated within the scientific community. Priestley’s science was integral to his theology, and he consistently tried to fuse Enlightenment rationalism with Christian theism.
When did Joseph Priestley commit himself to the Ministry?
In his third year at Daventry, Priestley committed himself to the ministry, which he described as “the noblest of all professions”. Robert Schofield, Priestley’s major modern biographer, describes his first “call” in 1755 to the Dissenting parish in Needham Market, Suffolk, as a “mistake” for both Priestley and the congregation.
What did Priestley observe in the Bell Jar Experiment?
He observed that neither the candle got extinguished, nor did the rat die. Conclusion: Based on his observations, Priestley concluded that in the first case, the air in the bell jar got polluted by the candle and rat. However, in the second case, the plant reinstated the air that was spoiled by the candle and the rat.
