Joseph Priestley Performed an Experiment in Which - Fill in the Blank - Was Heated By Focusing Sun Rays On It Using a Convex Lens
Joseph Priestley in 1774, performed an experiment in which Red mercuric oxide (HgO) was heated by focusing Sun’s rays on it using a convex lens.
Priestley was one of the first scientists who discovered oxygen. Joseph Priestly prepared oxygen in 1774 by heating red mercury(II) oxide with sunlight focused through a lens. Burning lenses were used both by Joseph Priestley and Antoine Lavoisier in their experiments to obtain oxides contained in closed vessels under high temperatures. Priestley prepared many gases, including nitric oxide, nitrogen dioxide, carbon monoxide, carbon dioxide, nitrogen, oxygen, hydrogen, hydrogen chloride, ammonia, sulphur dioxide, some of which were first discovered by him, such as oxygen.
