The law states that the total enthalpy change during the complete course of a chemical reaction is independent of the sequence of steps taken. [2] [3] Hess's law is now understood as an expression of the fact that the enthalpy of a chemical process is independent of the path taken from the initial to the final state (i.e. enthalpy is a state ...
In 1830, Hess took up chemistry full-time, researching and teaching, and later became an adjunct professor of Chemistry at the St. Petersburg Academy of Sciences. [1] His most famous paper, outlining his law on thermochemistry, was published there in 1840. [3] His principle, a progenitor for the first law of thermodynamics, came to be called ...
Personally, I think that Hess's law sounds much better so I would keep the title and change the text back to Hess's throughout. Dirac66 ( talk ) 12:54, 19 October 2014 (UTC) [ reply ] On further thought, I decided to check my chemistry books as sources for this law, rather than look through dictionaries and grammar books for general laws of ...
[3] The result of Hess's meticulous work was published in the Proceedings of the Austrian Academy of Sciences, and showed the level of radiation decreased up to an altitude of about 1 kilometre (0.6 mi), but above that the level increased considerably, with the radiation detected at 5 kilometres (3.1 mi), being about twice that at sea level.

Benford's law : In many collections of data, a given data point has roughly a 30% chance of starting with the digit 1. Benford's law of controversy: Passion is inversely proportional to the amount of real information available. Bennett's laws are principles in quantum information theory. Named for Charles H. Bennett.
The Three Laws, presented to be from the fictional "Handbook of Robotics, 56th Edition, 2058 A.D.", are: [1] A robot may not injure a human being or, through inaction, allow a human being to come to harm. A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
Written in the form of twelve letters addressed to a woman in her grief at the loss of a relative. In his work, Hess put forward the following ideas: [2] The Jews will always remain strangers among the European peoples, who may emancipate them for reasons of humanity and justice, but will never respect them so long as the Jews place their own great national memories in the background and hold ...
Hess v. Indiana, 414 U.S. 105 (1973), was a United States Supreme Court case [1] involving the First Amendment that reaffirmed and clarified the imminent lawless action test first articulated in Brandenburg v. Ohio (1969). Hess is still cited by courts to protect speech threatening future lawless action. [2]
