Calculate the heat capacity of the unknown metal after each

Question Calculate the heat capacity of the unknown metal after each trial, then determine the average heat capacity of the unknown metal based on these three trials. Begin by calculating Q for water then use that information to calculate heat capacity for the metal using the equations in the Introduction section under the eScience tab procedure. Remember the heat lost by the water (-Q) is the heat gained (Q) by the metal. Also remember, you did not take the mass of the 40 mL of water you used, but you do know that the density of water is 1 g/mL. Also, pay attention to use proper units. Also remember, the final temperature of your calorimeter is the final temperature of BOTHyour metal and the water, since they should be the same temperature now.Use your specific heat value for your unknown metal to try and guess its identity. You will need to look up specific heat data tables online, but make sure you pay attention to your units, because some tables use different units to report specific heats. Think about your choice in terms of practicality as well. It is likely that your value will not be exact, since we are using somewhat crude experimental instrumentation. But take your best guess based not only on your value, but what makes sense that could be shipped in a kit like this. For example, it is probably not going to be something rare (expensive), dangerous/reactive, or toxic. Also, consider its physical appearance. Maybe even test some more simple properties, like magnetism, density (see Lesson 1), etc. You will not be penalized for an incorrect guess, but you can earn extra credit if you choose correctly and if you support your reasoning with a good explanation/evidence.
