This list contains acronyms, initialisms, and pseudo-blends that begin with the letter K.. For the purposes of this list: acronym = an abbreviation pronounced as if it were a word, e.g., SARS = severe acute respiratory syndrome, pronounced to rhyme with cars
Boltzmann constant: The Boltzmann constant, k, is one of seven fixed constants defining the International System of Units, the SI, with k = 1.380 649 x 10 −23 J K −1.The Boltzmann constant is a proportionality constant between the quantities temperature (with unit kelvin) and energy (with unit joule).
The district closed the school in late September 2007 to test the school for mold; [5] students attended Fleming Middle School. [5] In September 2007 Sheila Jackson Lee, a U.S. congressperson, had asked the Centers for Disease Control (CDC) and the Environmental Protection Agency (EPA) to visit Key.
A kilowatt-hour (unit symbol: kW⋅h or kW h; commonly written as kWh) is a non-SI unit of energy equal to 3.6 megajoules (MJ) in SI units, which is the energy delivered by one kilowatt of power for one hour. Kilowatt-hours are a common billing unit for electrical energy supplied by electric utilities.
kT (also written as k B T) is the product of the Boltzmann constant, k (or k B), and the temperature, T.This product is used in physics as a scale factor for energy values in molecular-scale systems (sometimes it is used as a unit of energy), as the rates and frequencies of many processes and phenomena depend not on their energy alone, but on the ratio of that energy and kT, that is, on E ...
The thermodynamic beta was originally introduced in 1971 (as Kältefunktion "coldness function") by Ingo Müller , one of the proponents of the rational thermodynamics school of thought, [5] [6] based on earlier proposals for a "reciprocal temperature" function. [1] [7] [non-primary source needed]
It was ranked by US News as the #13 best California Middle School and second best school in the Cupertino Union School District. [2] Kennedy Middle School was a National Blue Ribbon School awardee in 1993 [3] and a California Distinguished School in 2013. [4] It is also known for its exceptional high standards and test scores. As of the 2023 ...
The binding constant, or affinity constant/association constant, is a special case of the equilibrium constant K, [1] and is the inverse of the dissociation constant. [2] It is associated with the binding and unbinding reaction of receptor (R) and ligand (L) molecules, which is formalized as:
