A) If the final temperature is 22.1°C, what is the specific heat of the object? (2 sig fig)

B) Referring to the table, identify the material in the object

To determine the specific heat of an object, a
student heats it to 100 C in boiling water. She
then places the 45.8 g object in a 163 g aluminum
calorimeter containing 123 g of water. The
aluminum and water are initially at a temperature of
20.0°C, and are thermally insulated from their
surroundings.
