Tilstandslikningen for en idealgass

Årstidene påvirker lufttrykket

Den som fyller luft i et oppvarmet lokale må være spesielt oppmerksom på temperaturproblemstillingen. Hvis bilen har stått lenge i en oppvarmet garasje, vil nemlig luften inni dekkene oppnå omtrent samme temperatur som garasjeluften. Hvis du fyller 250 kPa i et lokale som holder 20 varmegrader og deretter kjører ut i 20 minusgrader, vil lufttrykket snart synke til rundt 210 kPa.

Men dette problemet kan altså løses ved overfylling. I dette tilfellet ville du oppnådd korrekt lufttrykk ved å fylle 290 kPa.
