Absolute partial pressure 101.325 kPa (1.00000 atm; 1.01325 bar) for each gaseous reagent — the convention in most literature data but not the current standard state (100 kPa). Variations from these ideal conditions affect measured voltage via the Nernst equation .
The CRC Handbook of Chemistry and Physics is a comprehensive one-volume reference resource for science research. First published in 1914, it is currently (as of 2024 [update] ) in its 105th edition, published in 2024.
Quantities, Units and Symbols in Physical Chemistry, also known as the Green Book, is a compilation of terms and symbols widely used in the field of physical chemistry. It also includes a table of physical constants , tables listing the properties of elementary particles , chemical elements , and nuclides , and information about conversion ...
Tables of Physical and Chemical Constants and Some Mathematical Functions is a scientific reference work. First compiled and published in 1911 by the physicists G. W. C. Kaye and T. H. Laby, it is more commonly known as Kaye and Laby. [1] It is a standard textbook for scientists and engineers.
From 1860 to 1861 he taught natural sciences at the Providence Conference Seminary, East Greenwich, Rhode Island, followed by a teaching position at the Delaware Literary Institute in Franklin, New York until 1867. That year he became professor of physics and chemistry at the Antioch College, where he stayed until 1870.
differential (e.g. ) varied depending on context differential vector element of surface area A, with infinitesimally small magnitude and direction normal to surface S: square meter (m 2) differential element of volume V enclosed by surface S: cubic meter (m 3)
The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.
The standard state of a material (pure substance, mixture or solution) is a reference point used to calculate its properties under different conditions.A degree sign (°) or a superscript Plimsoll symbol (⦵) is used to designate a thermodynamic quantity in the standard state, such as change in enthalpy (ΔH°), change in entropy (ΔS°), or change in Gibbs free energy (ΔG°).
