A rigid adiabatic container in a room with a barometric pressure of 100 kPa is divided into two unequal volumes as shown. V1 = 0.108 m3 and contains air (R = 0.2870 kJ/kg-K, k = 1.40) at a gauge pressure of 32 kPa and temperature of -3°C. V2 = 0.264 m3 and contains helium (R = 2.0769 kJ/kg-K, k = 1.667) at a vacuum pressure of 40 kPa and a temperature of 23°C. The membrane separating the two volumes bursts and the two gases mix together. When equilibrium is restored,
1- What is the gauge pressure in the container?
2- What is the final temperature? In C
