Specific Heat Capacity of Solid by the Method of Mixture
A calorimeter and stirrer are weighted and half of its volume is filled with water. Then it is again weighted to know the mass of water. The calorimeter is then placed inside the wooden box by surrounding the calorimeter with woolen clothes to prevent heat loss. The temperature of the calorimeter and its content are noted by the thermometer inserted into it. When the solid gains a constant temperature in the steam chamber, the calorimeter is brought below the chamber, its lid is opened and hot solid is put carefully in the calorimeter. The mixture is then stirred gently until the temperature of the mixture reaches a constant value.
To remove heat loss or gain, some wool or cotton clothes are kept in between calorimeter and the jacket. Here the mass of calorimeter with a stirrer, the mass of water, and initial temperature is noted. As the thermometer T1 shows constant temperature, the solid is transferred to the calorimeter and the final common temperature of the mixture is noted.
