: 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

with a standard table of specific heat capacities to identify the metal (e.g., iron, brass, or aluminum). Note that small deviations are normal due to heat loss to the calorimeter walls and the air during transfer ( 1.4.2 ). laboratornaia rabota 3 po fizike 8 klass

Below is a detailed guide for the most common version: . Objective : To measure the mass of the water and the metal body

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
