... trial two the specific heat capacity was found to be .113(cal)/(g Celsius) and for trial three the specific heat capacity was found to be .115 (cal)/(g Celsius). The same formula stated above was used but with different variables of initial water, final water, and mass variables. Next we calculated our average value of specific heat capacity by taking the sum ... of our three trials and dividing by three. The average was .111 (cal)/(g Celsius). The accepted value was .105 (cal)/(g Celsius). When taking the percent difference we used the formula (average-accepted)/(accepted) and came up ...
