1) A rigid tank of propane (C3H8) with a volume of 1.5 m3 is filled with 8 kg of gas at an initial temperature of 25°C. The container is then heated until the pressure is 400 kPa. Using Phase-Change (PC) Model properties from the TEST software, determine (a) the initial pressure and (b) the final temperature.

final answers should be:

a) p1= 285.6 kPA

b)T2= 134.3 C

2) A 20 m^3 tank containing carbon dioxide (CO2) is kept at a pressure of 500 kPa and a temperature of 25°C. A small leak develops in the tank, allowing some of the carbon dioxide to escape and the pressure to drop to 450 kPa while the temperature remains close to 25°C. Using Phase-Change (PC) Model properties from the TEST software, determine the mass of the carbon dioxide that has leaked from the tank.
