Explanation / Answer
From the law of conservation of energy,
The heat gained by the water in calorimeter = The heat lost by the metal
For trial 1,
Heat gained by the water, Qwater= Mass X specific heat of water X Temperature difference
= 40 g X 4.179 Jg-1C-1 X (26.9-26.3) C [ Specific heat of water is known to be 4.179 Jg-1C-1]
= 100.296 J
Heat lost by Metal = Mass X Specific heat of metal X Temp difference
= 18.8 g X Specific heat X (84.5-26.9) C
= 1082.88 g C X Specific heat
According to law of conservation of energy, 1082.88 g C X specific heat = 100.296 J
Therefore, Specific heat of metal = 0.093 J g-1 C-1
Trial 2
40 X 4.179 X (27.6-26.3) = 18.8 X Specific heat X (84.3-27.6)
Therefore, 1065.96 X specific heat = 217.308
Therefore, specific heat = 0.204 J g-1 C-1
Trial 3
40 X 4.179 X (28.2-26.3) = 18.8 X Specific heat X (84.2-28.2)
Therefore, 1052.8 X specific heat = 317.604
Therefore, specific heat = 0.302 J g-1 C-1
