    What is the definition of a calorie? How much water is present and what is the temp differential between -4C and the freezing point of water?

    1. Get the energy required to raise the temperature of the ice cube from -4 to 0 degrees Celsius
    2. Get the energy required to melt the ice cube into liquid water.
