Gas idealen konstante

Gas idealen konstante unibertsala bariable desberdinak lotzen dituen konstante fisiko bat da; bereziki bolumena, presioa, tenperatura eta materia kantitatea lotzen ditu.

Gehienetan konstantea gas idealen ekuazioan erabiltzen da. (R)

${\displaystyle PV=nRT}$

Gas idealaren modeloan molekulen bolumena zero dela onartzen da, eta partikulak euren artean interakzionatzen ez dutela.

Gasen konstante unibertsala ez da funtsezko konstante bat, arrazoi honegatik, unitate sistema praktikoenak hartuta, honek dira R-ren balioak:
