IIRC the temperature of the H2O doesn't change until the bonds have changed. There is a state of constant temperature during this phase change, often referred to as a temperature plateau. Therefore it melts @ 32F (assuming 1 atmosphere of pressure) after that the temperature of the liquid water will rise, but not until it has already melted.
