a) The heat gained by the water and calorimeter
Q = mc??w + mc??c = (0.08*4200*3.7) + (0.05*400*3.7)
= 2741.2J
b) The specific heat capacity of the metal
0.1*c*71.3=2741.2
C=2741.2/0.1*71.3 = 381.46JKg-1K-1
c) State the possible sources of error in the value of the s.h.c obtained in the above experiment.
- Heat loss as the metal was being transferred from the boiling water to the calorimeter.
- Error when reading the thermometer (parallax error)

70g of a solid initially at 25^oC was carefully dropped into water in a calorimeter at 60^oC. If the final
constant temperature of the water and the solid was 54^oC and the mass of water is 500g, determine the
specific heat capacity of the solid. Assume the heat absorbed by the calorimeter to be negligible. Take the s.h.c. of water = 4200JKg-1K-1.
