1.Solid solutions consisting of GaAs and InAs can be produced by equilibrating a gas mixture composed of Hf, HCI, InCI, GaCl and Asq. The composition of the solid solution is determined by the thermodynamic conditions of the system. In order to produce GaAs-InAs solid solution with a particular composition, how many intensive thermodynamic variables need to be fixed?
2. A system contains ice at 0°C and 1 atm. Calculate the change in the chemical potential of ice associated with the increase in the pressure from 1 atm to 2 atm. The density of ice is 0.915 g/cm’. Calculate the change in the chemical potential of water associated with the inctease in the pressure from 1 am to 2 atm. Ice is now in equilibrium with water at 0°C and 1 am. If the pressure in the system is increase to 2 atm, will ice melt, fieeze or remain unchanged?
