Question
Can ice coexist in equilibrium with water at 1 atmospheric pressure and –4°C?
Solution
No, ice cannot coexist in equilibrium with water at 1 atm and at a temperature of -4o C.
The solid can be in equilibrium with liquid phase only at temperature and pressure corresponding to the melting point. The melting point of ice at 1 atmospheric pressure is 0°C. Therefore, ice at 1 atmospheric pressure and –4°C temperature cannot coexist in equilibrium with water.
