    For 1kg of aluminium to be raised by 1K, it requires 920J. The block is 2kg so 920x2 = 1840J to raise the block by 1K. At 20C (298K) the block will have 1840 x 298 = 539120J, rounded up that's 540kJ.

    What is it you do not understand?

    Specific heat capacity is the energy the metal holds per degree Kelvin for every Kg.

    Convert degrees C to Kelvin and then multiply specific heat capacity and then mass to get the total energy.
