# Lord Kelvin & Kelvin scale

William Thomson, 1st Baron Kelvin. Lord Kelvin is widely known for determining the correct value of absolute zero as approximately −273.15 Celsius. The existence of a lower limit to temperature was known prior to Lord Kelvin, as shown in "Reflections on the Motive Power of Heat", published by Sadi Carnot in French in 1824, the year of Lord Kelvin's birth.

"Reflections" used −267 as an estimate of the absolute zero temperature. Absolute temperatures are stated in units of kelvin in his honour. On his ennoblement in 1892 in honour of his achievements in thermodynamics, and of his opposition to Irish Home Rule,[1][2][3] he adopted the title Baron Kelvin, of Largs in the County of Ayr and is therefore often described as Lord Kelvin. He was the first UK scientist to be elevated to the House of Lords. The title refers to the River Kelvin, which flows close by his laboratory at the University of Glasgow. His home was the imposing red sandstone mansion Netherhall, in Largs on the Firth of Clyde. Early life and work ... Kelvin. The kelvin is a unit of measurement for temperature. It is one of the seven base units in the International System of Units (SI) and is assigned the unit symbol K. The Kelvin scale is an absolute, thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics.

The kelvin is defined as the fraction 1⁄273.16 of the thermodynamic temperature of the triple point of water (exactly 0.01 °C or 32.018 °F).[1] In other words, it is defined such that the triple point of water is exactly 273.16 K. The Kelvin scale is named after the Belfast-born, Glasgow University engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907), who wrote of the need for an "absolute thermometric scale". Unlike the degree Fahrenheit and degree Celsius, the kelvin is not referred to or typeset as a degree. History Usage conventions This SI unit is named after William Thomson, 1st Baron Kelvin.

Lord Kelvin biography - Science Hall of Fame. Famous for: Devising the absolute temperature scale, now called the 'Kelvin scale' Formulating the second law of thermodynamics Working to install telegraph cables under the Atlantic. Lord Kelvin (William Thomson) was an eminent physicist with a wide range of interests and enthusiasms. Best remembered for his talent for theoretical mathematics, he also had a practical ability for solving problems. Thanks to his persistence and ingenuity, the first telegraph cable was successfully installed under the Atlantic Ocean.

Early life and education William Thomson was born at 21-25 College Square East in Belfast in 1824. Lord Kelvin's father became Professor of Mathematics at Glasgow University. In his teens he learned French well enough to read the work of eminent French mathematician Jean Baptiste Joseph Fourier. From 1841 to 1845 Kelvin attended Cambridge University. Professorship at Glasgow University After graduating, Kelvin worked in a Paris laboratory with physics professor Victor Regnault.

Previous | Contents | Next AFTER a long life of unwearied and unrivalled achievement, Lord Kelvin stands to-day in a place of universal honour, unquestionably the greatest and most revered man of science of our time. His grandfather was a Scottish Ulsterman, tenant of a small farm at Annaghmore, Ballinahinch, County Down.

His father, James Thomson , born there in 1786, intended first to become a Presbyterian minister, and studied at . But after taking his degree in 1812 he accepted an appointment as teacher in Belfast Royal Academical Institution, and became Professor of Mathematics when the collegiate department was added to that school. He received the degree of LL.D. from Glasgow University in 1829, and three years later was appointed Professor of Mathematics in the old College in High Street. Among the many books which he wrote, memoirs and text-books, Thomson's Arithmetic was in universal use for generations, and remains justly famous to the present day. William Thomson, Lord Kelvin. William (Thomson), 1st Baron Kelvin of Largs, physicist, mathematician, engineer and inventor, was born on 26 June 1824 in Belfast, Northern Ireland.

He was one of seven children of James Thomson (1786-1849), professor of mathematics, and his wife Margaret (d.1830), daughter of William Gardner. The family moved to Glasgow where William was educated before he entered Cambridge University. His first wife was Margaret Crum and he married secondly Frances Blandy but had no children. In 1846 he was elected Professor of Natural Philosophy at Glasgow and held that post until 1899. Burial and memorial window The Royal Society asked the Dean of Westminster if Kelvin could be buried in Westminster Abbey and he agreed. In 1913 a stained glass window, designed by J.Ninian Comper, was erected near the grave. "In memory of Baron Kelvin of Largs. His coat of arms and those of Glasgow University are shown. A photograph of the window and gravestone can be purchased from Westminster Abbey Library. KELVIN TEMPERATURE SCALE - Chemistry Glossary. Kelvin is a temperature scale designed so that zero degrees K is defined as absolute zero (at absolute zero, a hypothetical temperature, all molecular movement stops - all actual temperatures are above absolute zero) and the size of one unit is the same as the size of one degree Celsius.

Water freezes at 273.16K; water boils at 373.16K. [ K = C + 273.16°, F = (9/5)C + 32°]. This temperature scale was designed by Lord Kelvin (William Thomson, 1824-1907). Kelvin was a British inventor and scientist (he was born in Belfast, Northern Ireland in 1824). In addition to his work on temperature, Kelvin invented over 50 devices (including the mirror galvanometer, which detects and measures weak electric fields), discovered the second law of thermodynamics (the amount of usable energy in the universe is decreasing), and wrote hundreds of scientific papers. Thomson was knighted in 1866 (by Queen Victoria) and named Baron Kelvin of Largs in 1892. Temperature - Kelvin Scale. Kelvin Scale The Kelvin temperature scale (K) was developed by Lord Kelvin in the mid 1800s. The zero point of this scale is equivalent to -273.15 °C on the Celsius scale. This zero point is considered the lowest possible temperature of anything in the universe. Therefore, the Kelvin scale is also known as the "absolute temperature scale".

Whereas the Kelvin scale is widely used by scientists, the Celsius or Fahrenheit scales are used in daily life. The Kelvin temperature scale (K) was developed by Lord Kelvin in the mid 1800s. The zero point of this scale is equivalent to -273.15 °C on the Celsius scale. Lord Kelvin developed this scale with the help of a Carnot engine.

Kelvin Temperature Scale Definition - Definition of Kelvin Temperature Scale. Lord Kelvin Biography - Lord Kelvin Childhood, Life and Timeline. Lord Kelvin Childhood William Thomson was born on 26 June 1824 in Belfast, Ireland to mother Margaret Gardner and father James Thomson (a mathematics and engineering teacher at Royal Belfast Academical Institution).

William was the second child born in a family of four children. He lost his mother at a very young age of 6 in 1830. William was educated at home along with his elder brother James. In 1832 William’s father James Thomson was asked to join as a professor of mathematics at Glasgow which made the family relocate there in October 1833. William suffered from heart problems and was very ill to the brink of dying at the age of 9. Early Years Thomson started off with his work on mathematics getting inspired and influenced by French mathematician Jean Baptiste Joseph Fourier’s ‘Fourier series’. It was quite obvious that William would take up higher studies which was greatly supported and made easy by his father who was a renowned teacher. Career and Scientific Developments Honours.
