A sketch of the phase diagram of water is given below. Which statement describing the broken line, (E to F) and/or the diagram is false? Pressure Temperature B E A F At point E the water is all solid ice. O If heat is added to the ice at point E, the temperature of the ice increases until line AB is reached, then the temperature remains constant until all of the ice is melted into liquid. O If more heat is added upon reaching point F, the temperature will remain constant as the liquid water vaporizes. Another way to vaporize all of the liquid water at point F would be to increase the pressure. O Line AC is the vapor pressure curve, liquid and gas are in equilibrium. O Once all the ice has melted (at the intersection of the broken line and line AB) the temperature of the water increases as heat is added until point F is reached.
