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 ...
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).
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.
Thermodynamic beta is essentially the connection between the information theory and statistical mechanics interpretation of a physical system through its entropy and the thermodynamics associated with its energy.
Electric circuit with metal and a battery U. The arrows indicate the direction of the electric field E and the electric current density j.. Qualitatively, this relationship is based upon the fact that the heat and electrical transport both involve the free electrons in the metal.
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
is the thermal conductivity (W/(K·m)) of the sample; is the thermal resistivity (K·m/W) of the sample; is the cross-sectional area (m 2) perpendicular to the path of heat flow. In terms of the temperature gradient across the sample and heat flux through the sample, the relationship is:
The data should have a linear relationship, the equation for which can be found by fitting the data using the linear form of the Van 't Hoff equation ln K e q = − Δ r H ⊖ R T + Δ r S ⊖ R . {\displaystyle \ln K_{\mathrm {eq} }=-{\frac {\Delta _{r}H^{\ominus }}{RT}}+{\frac {\Delta _{r}S^{\ominus }}{R}}.}
