5. What are the physical properties of dry air at different temperatures and pressures?

**Tip**: Always verify if the values you are using for specific heat and other constants match the temperature and pressure conditions given.

Die Luft in einem Gefäß in Form eines Dreiecksprismas wird von einer Temperatur von 680 °C auf 26 °C heruntergekühlt. Im Anfangszustand beträgt der Druck im Gefäß 3.9 bar. Das Prisma ist 2 m hoch und besitzt als Grundfläche ein rechtwinkliges Dreieck, dessen Seiten am rechten Winkel beide eine Länge von 0.9 m haben. Benutzen Sie die Stoffwerte von trockener Luft bei einem Druck von 1 bar und einer Temperatur von 200 °C.
a) Wie groß ist der Druck im Endzustand?
b) Bestimmen Sie, wie viel Wärme bei diesem Prozess abgeführt wird.
c) Der Abkühlprozess findet in 1 Minute statt. Wie groß ist der Wärmestrom durch die Wände des Körpers?
