Guide questions 1. To allow the heat coming from the boiling water to reach the inner regions of the metal so that the whole mm has uniform temperature2. To avoid erroneous data because the adhering water would provide additional heat that is not accounted for in the working equation3. Advantage stirring helps achieve thermal equilibrium fasterDisadvantage it could cause erroneous data if its heat absorption is not accounted for in the working equations

1. 0 degrees Celsius.By examining its surface. If there is liquid water, we know that it is near the melting point and approximately 0 degrees celsius2. The equation accounts for mi being pure solid ice and not wet ice. The adhering liquid water possess additional heat that is not accounted for.Analysis1. No. A larger metal mass of the same shape would have a less surface area to mass ratio and thus, a less efficient heat transfer with the surroundings. Using these would make the experiment more susceptible to errors.2. No. Using hot water would result to a higher Tmix, a bigger change in T between the system and the surrounding, and a faster rate of heat loss. This makes the system less stable and erroneous.3. a. The inaccurate mi data caused by the melting of some of the ice mass before being placed in the calorimeter. A way around this is by putting the ice into a cooler immediately after weighing it.b. Non-uniform temperature of the metal mass. This could be avoided by immersing the metal mass in the boiling water for an adequately longer period of time.ConclusionIn performing the experiment, the specific heat of aluminium and brass has been determined with tolerable percent errors of 0.05% and 7.85%, respectively. In addition, the latent heat of fusion of water has been discerned with a minimum percent error of 0.5%.All of the objectives have been met as stated above.I think the experiment is very well designed because it helps the student understand the concept of heat and calorimetry in a systematic and feasible manner.In real life, particularly in chemical engineering, the concept of calorimetry is used to determine the amount of heat absorbed or released during a reaction process. This helps us compute for the required amount of heat to be supplied in a manufacturing process that involves chemical reactions.
