In a calorimetry experiment to determine the specific heat capacity of a metal block, the following data was recorded:

Quantity

Mass of the metal block

0.50 kg

Mass of empty calorimeter + Stirrer

0.06 kg

Mass of calorimeter + stirrer + water

0.20 kg

Mass of water

0.14 kg

Initial Temperature of metal block

55.5 ⁰C

Initial Temperature of water and calorimeter

22 ⁰C

Final Temperature of block- water system

27.4 ⁰C

Take the specific heat capacity of water to be 4186 J/Kg °C.

The calorimeter and stirrer are made of Copper. Specific heat capacity of Copper is 387 J/Kg °C.

Ignore the mass of the stirrer.

Use the data and the information given to:

a) Calculate the specific heat capacity of the metal block. (Please show ALL work for full credit)

b) From your result above, what is the metal block probably made up of?

c) Calculate the final temperature of the block – water system if the mass of the water in the calorimeter is increased to 0.50 kg (the same as the mass of the metal block).
