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)

P V = n R T {\displaystyle PV=nRT}

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

R-ren balioa

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