: To minimize heat exchange with the environment. Thermometer : To measure initial and final temperatures.

Quickly transfer the heated metal body from the boiling water into the calorimeter with cold water. Stir the water gently with the thermometer or a stirrer. Final temperature (

: To measure the mass of the water and the metal body. Measuring Cylinder (Beaker) : To measure water volume. Metal Body on a String : The substance being tested. Vessel with Boiling Water : To heat the metal body. Step 1: Preparation and Measurements Mass of the body ( ): Measure the mass of the metal body using the balance.

of cold water into the inner vessel of the calorimeter. Determine its mass (either by volume, where , or by weighing). Initial water temperature ( : To minimize heat exchange with the environment

The third laboratory work in the 8th-grade physics curriculum (specifically the widely used program) is titled "Measuring the Specific Heat Capacity of a Substance" ( 1.2.1 ). Another common variation for this grade level is "Determining Relative Air Humidity" ( 1.2.2 ).

The laboratory work is completed once you have calculated the specific heat capacity Stir the water gently with the thermometer or a stirrer
