Describe on the experimental treatment by which you can obtain the initial temperature of the unknown metal at 100.0 °C. How do you think you can prepare this metal at 100.0 C before you put it in the styrofoam cup calorimeter. Describe your experimental method in detail.

Answer 1

If you use pure water and the atomospheric pressure is 1 atmosphere, the water will boil at 100 C. Place the metal in the water and let it stay there with the water boiling for a few minutes. It will be at the same temperature as the water.
