Benjamin Thompson, Count Rumford, is best known for the cannon boring experiments that confirmed to him that heat was what we would call molecular motion. Some will also know him as the founder of the Royal Institution in London. He was, however, a much more colourful character than these details suggest. Born in Massachusetts in 1753, he had Impressed by the cannon-boring experiments of Count Rumford, James Prescott Joule recognized Rumford's discovery needed to be quantified by an experimental determination of the mechanical equivalent Count Rumford's Contribution. Benjamin Thompson, Count Rumford (1753 - 1814) was an Anglo-American physicist and inventor whose challenges to established physical theory were part of the 19th century revolution in thermodynamics. James Prescott Joule (1818 - 1889), an English physicist, calculated in 1843, a few decades after Rumford ジェームズ・プレスコット・ジュール （ 英: James Prescott Joule, 1818年 12月24日 - 1889年 10月11日 ）は イギリス の 物理学者 。. 生涯、大学などの研究職に就くことなく、家業の醸造業を営むかたわら研究を行った。. ジュールの法則 を発見し、 熱の仕事当量 の After Count Rumford (Benjamin Thompson) and James Prescott Joule had shown the equivalence of mechanical energy and heat, it was natural that engineers believed it possible to make a "heat engine" (e.g., a steam engine) that would convert heat completely into mechanical energy. Sadi Carnot considered a hypothetical piston engine that contained The cannon boring experiment of Count Rumford, where eight kilograms of water were boiled by metal on metal friction, is investigated. Consideration of this dramatic demonstration can enrich classroom discussions of calorimetry, units of measure, elements, and thermodynamics. A section pertaining to use of the article in the classroom appears after the experiment is discussed.
