Shown to the right is a P-V diagram for a newly discovered substance called Stuffium (Mstuffium= 100 kg/kmol). You conduct experiments with Stuffium using a variable volume container that is fitted with an injection port. PART A: You inject 250 g of pure Stuffium into a completely empty variable volume container with a starting volume of 1 m³. (a) At an equilibrium temperature of 400 K, determine the specific volume (in m³/kg) and pressure (in atm) of the contents at equilibrium. (b) Following from part (a), you isothermally increase the volume of the container until you have a saturated liquid. Determine the pressure (in atm) and the specific volume (in m³/kg) at equilibrium under these conditions. 10 8 7 620 K 550 K L+V 450 K 3. 400 K S+V 300 K 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 Specific Volume (m/kg) Pressure (atm) 2.
