Experiment Nine The Specific Heat of a Metal
DATA:
1. Mass of the metal sample.
10.138
2. Mass of water in calorimeter. 18.537
3. Initial temperature of metal sample. 94 °C
4. Initial temperature of water in calorimeter. 28 °C
5. Final temperature of water and metal. 31___"C
CALCULATIONS:
1. Calculate the changes in temperature of the water (aT water) and
of the metal (ATmetal).
T =temperature final - temperature initial
