Question

The density of liquid nickel at 1728K, its normal melting point at 101,325 Pa = latm, is 7.77 g/cm2. Its volume coefficient at expansion, a is 1.42 x 10-K. Calculate the increase in the free energy of liquid nickel at 2100K when the pressure on it is increased from 101,325 Pa to 10MPa. Find the activity of nickel in the high-pressure state. If the vapor pressure of pure liquid nickel (at 101,325 Pa) is 53.77 Pa at 2100K, calculate its vapor pressure in the high-pressure state. State any assumptions made. The atomic weight of nickel is 58.71.
