3. Use the data from Trial #1 to calculate the specific heat of the unknown metal object (cobj), in units of J ̊C−1 kg−1. Show your calculation and record the result below.

1. Measure the mass of your metal object, and record the value below. Then place the metal
object in the pot of boiling water at the front of the room.
50.5
mass of metal object =
2. Remove the inner cup from the calorimeter, and slide the ring off of the inner cup. Measure
the total mass of the inner cup and stirring rod (both are made of aluminum). Record your
value below.
85.5
total mass of inner cup and stirring rod =
3. Add tap water to the inner cup so that it is about two-thirds full. Measure the total mass of
the inner cup, stirring rod, and water. Record your value in Table 1 below.
