The Celsius scale, previously known as the centigrade scale, is a temperature scale used by the International System of Units (SI).
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
In physics, the electronvolt (symbol eV, also written electron-volt and electron volt) is a unit of energy equal to approximately joules (symbol J).
The Fahrenheit scale is a temperature scale based on one proposed in 1724 by Dutch-German-Polish physicist Daniel Gabriel Fahrenheit (1686–1736).
In thermodynamics, the Gibbs free energy (IUPAC recommended name: Gibbs energy or Gibbs function; also known as free enthalpy to distinguish it from Helmholtz free energy) is a thermodynamic potential that can be used to calculate the maximum of reversible work that may be performed by a thermodynamic system at a constant temperature and pressure (isothermal, isobaric).
The joule (symbol: J) is a derived unit of energy in the International System of Units.
The Kelvin scale is an absolute thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics.
The kilocalorie per mole is a unit to measure an amount of energy per number of molecules, atoms, or other similar particles.
kT is the product of the Boltzmann constant, k, 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 (see Arrhenius equation, Boltzmann factor).
The mole, symbol mol, is the SI unit of amount of substance.
The term phase transition (or phase change) is most commonly used to describe transitions between solid, liquid and gaseous states of matter, and, in rare cases, plasma.
SI derived units are units of measurement derived from the seven base units specified by the International System of Units (SI).
