- Figure 2 shows the equipment a student used to determine the specific heat capacity of iron. The iron block the student used has two holes, one for the heater and one for the thermometer. Figure 2 square o square 012 1 Before the power supply was switched on, the thermometer was used to measure the temperature of the iron block. The student left the thermometer in the iron block for a few minutes before recording the initial temperature. Suggest why. [1 mark] __
