Post Lab Questions Water is known to absorb to heat energy according to the following equation: mcAT. Where q is the amount of heat energy gained or lost by water. The mass of the water is symbolized by m, and AT is the temperature gained or lost. The specific heat capacity of water is c and the value of 4.184 J/goCfor water. Given this equation, it is possible to monitor the temperature change of the water, measure its mass, and calculate the amount of heat energy gained or lost by water. Calculate the heat gained by water in each of the ten experiments in part 1 of the lab and enter the data in data table 3. Based on this, determine the heat lost by the aluminum bar, and then calculate an experimental value for the specific heat of aluminum using the equation above. Data Table 3 0.696 759.47 -759.47 814.46 66648 4666.418 0.577 -934.72 0.8 d6 934.72 858.51 0.74 94.10 -898.21 Average CaterExplanation / Answer
Cliterature means the theoretical specific heat of aluminium which is 0.902 J/gC.
The experimental average value you have got is 0.7451 J/gC
% Error = [modulas of (Experimental value -Theoretical value) / Theoretical value] x 100
= [modulas of (0.7451-0.902) / 0.902 ] x 100
= 17.39 %
