Why was the calorimeter insulated?
I think it is because if the calorimeter is not insulated then the heat that is released may affect the actual result of the experiment.
Why do you think the the heating apparatus was coiled? (wound in circles).
Because the heat can transfer around the apparatus more easily and the water can heat up quicker.
Why do you think the vessel we held the water in was made of aluminium (Al) and not some other material.
Because Aluminium doesn't transfer heat like iron so it will be easier to remove the water if the heat is very high and we won't burn ourselves.
If you had to pick another material to make the vessel out of what would it be? and why?
I would choose a material that can capture heat well and won't heat up itself during the experiment, maybe I would choose copper due to it's great heat capacity and conductivity.
Would you expect the value we measure for the SHC of water be exactly 4200 J / kg / K? Justify your answer.
Yes i expect the answer to be 4200J/kg/K, because that is the exact amount of energy required for the water to rise up by 1 degree Celsius.
