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
mass of aluminium block = 2.0 kgpower of heating element = 420 Wtime of heating = 95 sinitial temperature of block = 19.5 °Cfinal temperature of block = 40.5 °Ca. Calculate the value of the specific heat capacity of aluminium given by this experiment.(c) In the experiment in (b), no attempt is made to prevent loss of thermal energy from the surfaces of the block. Suggest two actions the student could take to reduce the loss of thermal energy from the surfaces of the block.
