If the student has a thermometer that detects differences of 1°C or greater, will they be
able to measure a difference in temperature after adding the aluminum to the water?
Yes, they will definitely see a change because the temperature will increase by several degrees O.
O No, they will probably not see a measurable change, because the temperature will increase by
less than one degree C.
