Question

labeling the parts of a calorimeter this part insulates the reaction chamber from the transfer of heat to or from the surrounding environment. this part contains a known amount of water, which is placed there before the experiment starts. this part is where the metal is placed at the beginning of the experiment. this part is used for measuring the initial and final temperatures of the water.

Explanation:

The insulating part is the outer - layer structure that reduces heat exchange. The part with water is the inner chamber. The part for placing metal is also the inner chamber where the reaction occurs. The temperature - measuring part is the thermometer.

Answer:

1. Outer - layer structure insulates the reaction chamber from heat transfer to or from the surrounding environment.
2. Inner chamber contains a known amount of water.
3. Inner chamber is where the metal is placed at the beginning of the experiment.
4. Thermometer (A) is used for measuring the initial and final temperatures of the water.
