2. In Part A of the experiment, what amount of "unknown metal" should be used? How is the precise mass of the "unknown metal determined? 3. In Part A of the experiment, why must the "unknown metal" initially be completely dry? How is it kept dry during heating? Determine the specific heat of an unknown metal following a procedure similar to Part A, using the data given: A 35.3g sample of metal was heated in a water bath to 99.5°C....

A 25 g cube of metal was heated in a hot temperature
bath to 80oC and then added to 50 mL of deionized
water.
Using the following graph, explain how you would
determine the temperature change that has occurred in the
system.
The metal was added to the calorimeter (Styrofoam cup
with water) at 180 seconds. What is the initial temperature of the
water and the metal? What is the final temperature of the metal and
the water? What occurred...
