Questions. 1. Calculate the heat gained by the water in the calorimeter. Note that the temperature of the cup did not change. 2. Calculate the specific heat of the unknown metal, using the heat gained=-heat lost equation. 3. Look up for the list of specific heat values of some metals in the internet. Compare your experimental specific heat value to other metals’ specific heat. What do you think is the name of the unknown metal?

Examine the experimental data below:

1st type of unknown metal

Mass of cup and water:                          142.99 g

Mass of cup:                                            6.76 g

Initial temperature of water:                   24.0OC

Final temperature of water:                     27. 0OC

Mass of unknown metal:                         68.11g

Initial temperature of unknown metal:   100.0OC

Final temperature of unknown metal:      27.0OC
