Answer 1

It seems that you are asking me to help you with a physics experiment. The question is in Ukrainian, which is not the language commonly spoken in your location. I can understand and communicate fluently in Ukrainian, as well as other languages such as English, 中文, 日本語, Español, Français, Deutsch, and more.

The equipment you have listed is used to determine the specific heat capacity of a substance in a solid state. The specific heat capacity is the amount of heat energy required to raise the temperature of one gram of a substance by one degree Celsius. The procedure of the experiment is as follows :

1. Measure the mass of the metal body with a string using the balance and weights. Record the mass as m1. 2. Measure the mass of the empty calorimeter using the balance and weights. Record the mass as m2. 3. Fill the calorimeter with water until it is about three-quarters full. Measure the mass of the calorimeter with water using the balance and weights. Record the mass as m3. 4. Calculate the mass of water in the calorimeter by subtracting m2 from m3. Record the mass as m4. 5. Measure the initial temperature of water in the calorimeter using the thermometer. Record the temperature as t1. 6. Boil some water in the electric kettle. Carefully transfer the metal body with a string into the boiling water. Leave it there for about 10 minutes to ensure that the metal body reaches the same temperature as the boiling water. 7. Measure the temperature of the boiling water using the thermometer. Record the temperature as t2. 8. Quickly and carefully transfer the metal body from the boiling water to the calorimeter with water. Use the paper towels to dry the metal body if necessary. Stir the water in the calorimeter with the stirrer to ensure uniform temperature distribution. 9. Measure the final temperature of water and metal body in the calorimeter using the thermometer. Record the temperature as t3. 10. Calculate the specific heat capacity of the metal body using the formula: c = (m4 * c4 * (t3 - t1)) / (m1 * (t2 - t3)), where c is the specific heat capacity of the metal body, c4 is the specific heat capacity of water (4.18 J/g°C), and m1, m4, t1, t2, and t3 are the values measured in the previous steps.

I hope this helps you with your experiment. If you have any questions, feel free to ask me.
