Inventor of the Law of Conservation of Energy - Joule

James Prescott Joule (born in Salford, England, December 24, 1818 - died in Greater Manchester, England, October 11, 1889 at the age of 70 years) is a British scientist. He is known as the framers of the Law of Conservation of Energy, which states, "Energy can not be created nor destroyed." He was an English scientist with an interest in physics. With the trial, he managed to membuktkan that heat (calories) is nothing but a form of energy. Thus he managed to break the caloric theory, the theory that heat as a substance flow. One unit of energy-Joule-named it.
Law of conservation of energy is one of the laws of conservation of energy including kinetic and potential energy. This law is the first law of thermodynamics. Law of Conservation of Energy (first law of thermodynamics) reads: "Energy can be transformed from one form to another but can not be created or destroyed (energy conversion)". G.
Viewed from the perspective of physics, every physical system containing (alternatively, save) some energy; exactly how much is determined by taking the sum of a number of specific equations, each designed to measure the stored energy in particular. In general, the energy known to the observer changes the nature of every object or system. There is no uniform way to show energy;
In physics, the law of conservation states that a particular measurable property of an isolated physical system does not change while the system is changing. Here is a list of some of the laws of conservation that never showed incorrect. (Actually, in general relativity, energy, momentum, and angular momentum is not conserved because no common indentation wakturuang "manifold" which does not have a murder to translational symmetry or rotation).
James was the second son of five children. He came from a wealthy family. His father, Benjamin Joule, is a businessman who has breweries. Although coming from a wealthy family, but James could not attend school as children generally. James suffered a minor spinal disorder, which made him have a lot of rest at home. Because they can not go to school, the father had to find a tutor to teach James at home. Due to poor health, James grew up a quiet and shy.
As a child of a wealthy businessman, James may be said to be doing anything. He is free to read various kinds of books she likes. James is very interested in electricity. He is frequently sinister experiment by passing a small electrical current flow to the body of his servants. See James so fond of science, then at the age of 16, his father sent James to the University of Manchester. There he followed some scientific training taught by John Dalton. Returning from training science, father James was a private in the lab building basement for his son. In the laboratory, James perform various experiments to find the relationships between heat and electrical energy.
In 1840, James published a scientific paper about the heat generated by the electric current. Then in 1843, he published a continuation of his scientific work on how to turn work into heat. He conducted experiments using a treadle wheel. James finally from there to formulate the concept of equality physics mechanical energy and heat energy. Four years later, he succeeded in formulating the law of conservation of energy, which is the first law of thermodynamics law. The law states that energy can not be created or destroyed, but can be changed from one form of energy into other forms of energy.
In 1847 James met with Lord Kelvin or William Thomson, in the discussion of science. Lord Kelvin interested in James discoveries and scientific works ever published. He also invited James to work together. Of cooperation, it gives birth to a physics concept called the Joule-Thomson effect. Joule-Thomson effect and then developed into a science of studying the properties of matter at very low temperatures. Cryogenic Science called it.
In science or engineering physics, is the study of cryogenic materials with very low temperatures (below -150 ° C, -238 ° F or 123 K). The science of studying how to produce and behavior of materials at those temperatures. In discussing cryogenic, do not use Fahrenheit or Celsius temperature scale commonly used in the community, but rather use the Kelvin scale (initially used Rankine scale).
