By investigating all the aspects of this experiment, it is indicated that calcium chloride can't be justified to be whether it is effective to use for a heat and eat meal. As evident on the results, calcium chloride has been experimented with differentiation of the amount. In theory, these groups of data were supposedly to show a trend. However, as errors were recorded, this varies the evaluation.
As directed in the graph/table, there are no direct trends or patterns. Evidently, there is no specific water temperature. The initial temperature varies from 22C to 26C, which indicates that the tap water temperature is all different. However, this may be an error of reading the thermometer incorrectly. In addition, there wasn't a significant pattern …show more content…
In theory, the finishing temperature for the experiment was supposed to be higher in terms of the amount of calcium chloride used. For example, the 5g CaCl2 experiment was supposed to have a higher temperature in comparison to the 2.5g experiment. However, the data evidently proves that this wasn't the case. The experiment that contained 20g of calcium chloride ended on 51C. However, 17.5g experiment had 53C and the experiment before results showed that the temperature was 57C. There were many other cases of this error. This proves the inconsistency that occurred. Furthermore, it was also discovered that there was a dramatic decrease/ increase in temperature in some cases. Supposedly, all datas are supposed to have an exothermic …show more content…
It was evident that while collecting the calcium chloride, there were drops on the scale, meaning that there would be a decrease in the amount of chemical. The issue is that only some experiments out of the 8 had this problem, meaning that there would be errors within the whole data set (decrease the temperature, as the water has less chemical to react with), influencing the others. Furthermore, it was discovered that there were continuous spillage of the solution as the experiment was happening. As the thermometer entered the solution, there were overflows, consequently the temperature decreasing then starting to increase again. As a result, there was an inconsistency in all of the data. In addition, it could be hypothesised that this could've effected the saturated effect. Near the end of the experiment, chemicals were found at the bottom of the test tube, not dissolved. Unfortunately, this also results in a dramatic change in the temperature. In relation to the spillage of the solution, when a product is saturated, it is stated that it occurs as there isn't enough water to react. As the solution was spilled, which includes the water, it drops the 20ml of the water level. Hence the data showing a dramatic temperature fluctuation due to all the errors and relationships. Moreover, there could've been a simple error in reading the thermometer. It could
