Sulphur melts at 119.0 °C at 1 atm, and AHfusion = 55.2 J/g. Densities are 1.811 g/ml (liquid ), and 2.050 g/ml (solid). In the Frash process, molten sulphur is pumped from underground deposits at 6 atm total pressure. What must the minimum temperature be ? ( 1 J = 9.87 x 10-³ liter atm ) Aluminium expands slightly on melting, and AV = + 1.90 x 10-5 liter / g. The melting point is 658 °C, and AHfusion = 393 J/g. A sensitive probe is being developed to determine very high pressures, by measuring the melting temperature. A change of 0.001 °C can be detected. What change in pressure does this represent? ( 1 J = 9.87 x 10-³ liter atm)

Transcribed Image Text:Sulphur melts at 119.0 °C at 1 atm, and AHfusion = 55.2 J/g. Densities
are 1.811 g/ml (liquid), and 2.050 g/ ml (solid). In the Frash process,
molten sulphur is pumped from underground deposits at 6 atm total
pressure. What must the minimum temperature be ? ( 1 J = 9.87 x 10-³
liter atm)
Aluminium expands slightly on melting, and AV = + 1.90 x 10-5 liter / g.
The melting point is 658 °C, and AHfusion = 393 J/g. A sensitive probe is
being developed to determine very high pressures, by measuring the
melting temperature. A change of 0.001 °C can be detected. What change
in pressure does this represent? ( 1 J = 9.87 x 10-³ liter atm)
