Advanced Physics A rigid tank with a volume of 4 m3 contains a gas, whose molar mass is 40 kg/kmol. The The gas has a pressure of 7 bar and a temperature of 47 C (State 1). Suddenly the tank damages (pierces) and the gas escapes. When the tank is repaired, the amount of gas in the tank has decreased, while the pressure and temperature have been reduced to 4 bar and 27 \"C (State 2) A) What is the specific volume v1 of State 1, in m3/kg? B} What is the mass of gas m1 of State 1, in kg? C) What is the specific volume v2 of State 2, in m3/kg? D) What is the mass of gas m2 of State 2, in kg? E) What is the mass of gas that has escaped m leak, in kg? F) What is the volume Vleak that the filtered gas occupies in ambient conditions Patm=1 bar and Tamb=20 EC, in m3
