Question
When a piece of unknown metal weighing 15.20 grams, and at a temperature of 57.10 °C, is
placed in a calorimeter containing 37 g water at 20.40 °C, the temperature increases to 22.10 °C.
As the heat capacity of the calorimeter is 105.30 J K, what is the specific heat of the unknown
metal in J g K?
Do not write units, only enter numerical values,
Use two digits at most for decimal numbers, and use dot () as decimal separator (i.e. two-point-
fifty should be entered as 2.50). Do not use comma (,) as decimal separator.
