Procedure:

1. 1. Measure the mass of the calorimeter using ​ (a)   and record the value in the result and discussion part.

2. 2. Fill half of the inner container of the calorimeter with water and measure ​ (b)   of the calorimeter with the water. Record the value in the result and discussion part.

3. 3. Calculate the mass of ​ (c)   inside the calorimeter and record the value in the result and discussion part.

4. 4. Measure the initial temperature of the water inside the calorimeter using a ​ (d)   and record the value in the result and discussion part.
