Mixing Warm and Cold Water Data Sheet

 Data Sheet

  Cold Water (Probe 1) Hot Water (Probe 2)
Minimum Temperature (C)    
Maximum Temperature (C)    
Change in Temperature DT (C)    


  1. Calculate the heat gained by the cold water and the heat lost by the hot water by the equation: Q = DT * m * c where m = 50 g of water and c = 4.184 J/gC for water.

  2. Calculate the percent difference of the heat gain and the heat loss:
    % Difference = [(heat lost - heat gained)/ heat lost] * 100
