1 The calorimeter need to keep the heat . the external surface will make sure heat stay in the device
2 the coil surface have insulating effect. So it keeps heat inside it
3 the water need to be heat up in a short time. And aluminum can conduct heat better
4 copper. Because the thermal conductivity is higher then aluminum.
5 Yes, if we measure that every time the temperature went up one celsius degree, the measure of heat will be 4200 joule.
