A quantity of a substance that contains the same number (known as the Avogadro number) of molecules as the number of atoms contained in exactly 12.000 g of carbon-12 ( 12 C). This ...
work function (electronics)
Science; General science
A quantity with the dimensions of energy which determines the thermionic emission of a solid at a given temperature. The thermionic electron current density J emitted by the ...
Planck's constant
Science; General science
A quantity, designated by the letter h , which occurs repeatedly in those fundamental formulas of physics that describe the microworld, the world of atoms and nuclei and ...
