1. Why was the calorimeter insulated?
The reason why the calorimeter was insulated, I think it's because, in order to achieve the accurate result, we need the process to be perfectly correct, so we should make sure the heating process will proceed only inside the calorimeter, and the heat won't come out.
2. Why do you think the the heating apparatus was coiled? (wound in circles).
I think it's because the heat can go through the apparatus more easily and also it's a more effective way to heat up the water.
3. Why do you think the vessel we held the water in was made of aluminium (Al) and not some other material.
I think aluminum can conduct the heat better, so that the water will be heat up in a short time.
4. If you had to pick another material to make the vessel out of what would it be? and why?
I would use copper. Because the thermal conductivity is even better than aluminum.
5. Would you expect the value we measure for the SHC of water be exactly 4200 J / kg / K? Justify your answer.
Yes, I think so. Because I expect if we measure it, every time the temperature goes up one celsius degree, the measure of heat will be 4200 joule.
