a 1.9 kg block of iron at 22c is rapidly heated by a torch such that 16kJ is transferred to it. what temperature would the block of iron reach (assuming the complete transfer of heat and no loss to the surroundings). if that same amount of heat (16kJ) was quickly transferred to a 860 g pallet of copper at 27°C what temperature with the copper reach before it begins losing heat to the surroundings? Use the equation for heat capacity in the following heat capacity values:
