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)    

Questions:

  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
