Determining the specific heat of aluminum: let's do an experiment

Measure the data needed to determine the specific heat of aluminum in the experiment.

1. Assemble the test device

2. Measure the masses of the test object, the calorimeter cup and the cold water

Enter the data in the table below. One of the cells in the table must be filled by calculation.

Test data

Test object mass $m_{k}$ ( $k g$ )
Mass ( $k g$ ) of the aluminum calorimeter cup
Total mass of cold water and calorimeter cup ( $k g$ )
Mass of cold water $m_{v}$ ( $k g$ )

3. Measure the temperature of hot and cold water. Warm the test piece in a cup with hot water

Place the thermometers according to the situation shown in the photo in a larger cup with hot water and in the calorimeter. When heating the test object, you should stir the water from time to time and try to make it so that the test object is completely heated (because the heat takes time to spread to the center of the test object).

Enter the measured temperatures in the table below.

Test data

Initial temperature of cold water $t_{v 1}^{\circ}$ ( $^{\circ} C$ )
Initial temperature of the test object (hot water temperature) $t_{k 1}$ ( $^{\circ} C$ )

4. We place the examined body in the calorimeter, measure the final temperature of the warming cold water

Carefully lift the test piece from one container to another. However, this should be done quickly enough so that it does not cool down. The temperature of the cold water can be measured after the test object has completely cooled (it takes time for the heat to reach the water from the test object, so the temperatures of the test object and the water in the calorimeter equalize).
