Case 3| 80.0 g| 285.1 g| 88°C| 11°C| 12.9°C| -75.1 C°| +1.9 C°|
Case 4| 80.0 g| 142.3 g| 73.4°C| 0°C| 3.8°C| -69.6 C°| +3.8 C°|
CALCULATIONS PROCEDURES A and B:
| Experimental|
Case 1| 0.341 J/g C°|
Case 2| 0.375 J/g C°|
Case 3| 0.377 J/g C°|
Case 4| 0.407 J/g C°|
bonny:| 0.375 J/g C°|
Type of material:| Copper, 0.386 J/g C°|

The table shows some precise heats of common metallic elements:
Metal| Specific Heat (J/g?C)| Metal| Specific Heat (J/g?C)|
aluminum| 0.901| silver| 0.234|
marque| 0.450| gold| 0.129|
zinc| 0.390| lead| 0.128|
copper| 0.386| | |
Questions PROCEDURES A and B:
1.
In every trial, who deviated temperature more, the metal or the water? Did it subject whether it was initially hot or cold? Why?
The metal always had a larger change in temperature than the water, no matter whether the metal started hot or cold. This is because the metal has often less mass than the water in each trial.
In general, the part of the system with less mass will change temperature more.
2. Of the four trials, transfer to the first row of this column the data for the trial that came closer to the theoretical value:
