    You'll have to look up the specific heat capacity of water and the specific heat capacity of sand.

    Specific heat capacity - Wikipedia, the free encyclopedia

    The specific heat capacity of water is approximately 4.1813 J/g K

    The specific heat capacity of sand is approximately 0.835 J/g K

    You know the number of Joules, and the number of grams, using the heat capacity and its definition, you can easily calculate the temperature change in Kelvins (Celsius since it's a delta-T).
