Voltaic pile given by Volta to Faraday, 2000
Royal Institution, London, England. A voltaic pile given by Alessandro Volta, its discoverer, to Michael Faraday. A voltaic pile consists of alternating disks of dissimilar metals, with an electrically conducting medium--typically brine-soaked blotting paper--between pairs of disks. A voltaic pile was the first device to produce electricity from a chemical change. Previously only static electricity generators were used.
Vessels used in Faraday's electrochemical investigations, 2000
Royal Institution, London, England. Vessels used by Michael Faraday in discovering the first and second laws of electrolysis, linking the mass of substance deposited during electrolysis and the quantity of electric charge employed.
Faraday's apparatus for the electrolysis of water, 2000
Royal Institution, London, England. Apparatus used by Michael Faraday for the electrolysis of water. Each of the product gases--hydrogen and oxygen--collect in one of the slightly slanted cylinders, enabling one to measure the amount of each gas evolved.
Faraday's gas diamagnetism studies, 2000
Royal Institution, London, England. Each sealed bulb contains a different gas. Faraday investigated the effect of a magnetic field on each gas. A diamagnetic substance is one that is repelled by a magnetic field.
Faraday's "electric egg", 2000
Royal Institution, London, England. Michael Faraday's "electric egg." Faraday passed electricity through gases enclosed in the "egg" and produced different colors, the predecessor of discharge tube experiments.
Faraday's sample of benzene, 2000
Royal Institution, London, England. Sample of benzene, isolated by Michael Faraday from the illuminating gas mains in London.
Faraday's gas liquefaction apparatus, 2000
Royal Institution, London, England. Apparatus used by Michael Faraday to liquefy gases, including natural gas (methane).
Reconstruction of Faraday's laboratory, 2000
Royal Institution, London, England. Reconstruction of Michael Faraday's laboratory.
Faraday's watch, gift from Davy, 2000
Royal Institution, London, England. Faraday's watch, given to him by Humphry Davy, who had hired Faraday to work at the Royal Institution. In addition, two small magnets.
