A1.6 kg block of iron at 28 "Cis rapidly heated by a torch such that 18 kJ 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 (18 k.J ) was quickly transferred to a 880 g pellet of copper at 22 "C, what temperature would the copper reach before it begins losing heat to the surroundings? Use the equation for heat capacity and the following heat capacity values: me,AT 0.450 J/(g- "C) 0.385 J/(g- "C) Express the final temperatures of the iron and copper in "C to two significant figures separated by a comma.
