  Specific Heat of Water vs. Specific Heat of Sand Science

  The sand was much warmer than the ocean. The last part of the walk was the paved parking lot. Ouch! That black asphalt was hot. Your feet made you promise to throw on some flip flops next time. Why, on the same day, are the temperatures of water, sand, and asphalt so different? Specific heat is the key.
