2024年12月20日 · 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 (/ dʒuːl /; [1][2][a] 24 December 1818 – 11 October 1889) was an English physicist. Joule studied the nature of heat and discovered its relationship to mechanical work. This led to the law of conservation of energy, which in turn led to the development of 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. He also formulated the Joule's law which deals with the transfer of …

2019年1月28日 · 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 was born in 1818 in Salford, England. He was tutored at home and was expected to go into the family brewery business, along with his brother, Benjamin. When James was 16 years old, both boys were sent to learn chemistry …

2018年5月21日 · 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 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.

James Prescott Joule was an English physicist, who studied the nature of heat, and discovered its relationship to mechanical work. This biography of James Joule provides information about his childhood, life, achievements, works & timeline.

James Prescott Joule, (December 24, 1818 – October 11, 1889), Fellow of the Royal Society, was an English physicist, born in Sale, Cheshire. He discovered that heat and mechanical energy are inter-convertible, and that transformations from one to the other occur in a fixed proportion, known as the mechanical equivalent of heat.

James Prescott Joule, an ‘amateur’ scientist and inventor, combined brilliant scientific thinking and innovation with the brewer’s interest in highly accurate measurements.
