A student carries out an experiment to find the specific heat capacity of aluminium. He uses an electric heater and a thermometer, inserted into separate holes in an aluminium block. The following data are obtained.
Mass of aluminium block = 2.0kg
Power of heating element = 420W
Time of heating = 95s
Initial temperature of block = 19.5°C
Final temperature of block = 40.5°C
Calculate the value of the specific heat capacity of aluminium given by this experiment.
