Pression
In physica, pression (denotate P o p) es le fortia applicate a o distribuite super un superficie.
Illo ha dimensions de fortia per unitate de area, P = F/A, o energia per unitate de volumine (densitate de energia). Pression es un specie de scalar quantitate physic. In thermodynamica, pression es proportional al producto de temperatura T e densitate numeric n, P = nkT, ubi k es le constante de Boltzmann. Un alternative formulation es PV = NRT.
