Hess's law of constant heat summation, also known simply as Hess's law, is a relationship in physical chemistry and thermodynamics [1] named after Germain Hess, a Swiss-born Russian chemist and physician who published it in 1840. The law states that the total enthalpy change during the complete course of a chemical reaction is independent of ...
Hess' law of constant heat summation (1840): The energy change accompanying any transformation is the same whether the process occurs in one step or many. [3] These statements preceded the first law of thermodynamics (1845) and helped in its formulation. Thermochemistry also involves the measurement of the latent heat of phase transitions.

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 ...
Some of President-elect Donald Trump’s most vulnerable Cabinet picks are racing to smooth out or overwrite past statements before contentious Senate confirmation fights.
Patel also was involved in efforts to bring some of the most-wanted terrorists to the U.S. for prosecution, and worked on Trump administration efforts to return dozens of U.S. hostages back home.

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 ...
