: 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. Mass of the water ( ): Pour about

The heat balance equation states that the heat gained by the water ( Qgaincap Q sub g a i n end-sub ) equals the heat lost by the metal body ( Qlostcap Q sub l o s t end-sub laboratornaia rabota 3 po fizike 8 klass

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 ).

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 ( Vessel with Boiling Water : To heat the metal body
