Sulphur can be recovered from underground elemental deposits via the Frasch process. In this process, superheated water (at 165°C and 2.5MPa) is pumped into the deposit and melts the sulphur, which is then lifted to the surface with compressed air. Assume the sulphur deposit experiences a total pressure of 6 atm from being under the cap rock. What is the minimum temperature required to melt the sulphur if: ● ● ● Melting temperature at 1 atm is 388.2 K AHfusion = 53.67 J/g Pliquid 1.811 g/mL Psolid = 2.050 g/mL
