James Joule was born in 1818, the son of Benjamin Joule (1784–1858), a wealthy brewer, and his wife, Alice Prescott, on New Bailey Street in Salford. Joule was tutored as a young man by the famous scientist John Dalton and was strongly influenced by chemist William Henry and Manchester engineers Peter Ewart and Eaton Hodgkinson .
James Prescott Joule, English physicist who established that the various forms of energy, such as electrical and heat, are basically the same and can be changed one into another. Thus, he formed the basis of conservation of energy, the first law of thermodynamics.
James Prescott Joule studied the nature of heat and established its relationship to mechanical work. He laid the foundation for the theory of conservation of energy, which later influenced the First Law of Thermodynamics.
May 21, 2018 · The English physicist James Prescott Joule (1818-1889) proved that mechanical and thermal energies are interconvertible on a fixed basis, and thus he established the great principle of conservation of energy.
James Prescott Joule was an English physicist who studied the nature of heat and discovered its relationship to mechanical work. This study later led to formation of the first law of thermodynamics.
James Prescott Joule (1818–89) is now rightly revered as one of the greatest scientists in the history of physics, due to his groundbreaking work in thermodynamics. However, this was not always the case—in his younger years, Joule struggled to be taken seriously by the scientific establishment.
James Prescott Joule experimented with engines, electricity and heat throughout his life. Joule’s findings resulted in his development of the mechanical theory of heat and Joule’s law, which quantitatively describes the rate at which heat energy is produced from electric energy by the resistance in a circuit.
