Adiabatic rigid tank (control mass) is divided into two nonequal volumes: A and B by a flexible membrane. Part A contains H₂O liquid at 7 kg, 220 kPa, , and at 25 °C, and part B is at sub‐atmospheric pressure under vacuum state condition with no mass and has a volume of 2 .

If membrane is ruptured by making a hole such that two systems reach a final equilibrium state at 25 °C:
