The African Adventures exhibit water system holds approximately 850,000 gallons (3.2x109 g) of water. The temperature swing from sunrise to about an hour before sunset can be as high as 1.8 °C. How much heat in kilojoules must be absorbed to result in that temperature increase? Assume that the specific heat capacity of the exhibit is 4.184 J/gC.
