Chemistry

A 1.5 kg block of iron at 32 ∘C is rapidly heated by a torchsuch that 14 kJ is transferred to it. What temperature would theblock of iron reach (assuming the complete transfer of heat and noloss to the surroundings)? If that same amount of heat (14 kJ ) wasquickly transferred to a 890 g pellet of copper at 31 ∘C, whattemperature would the copper reach before it begins losing heat tothe surroundings? Use the equation for heat capacity and thefollowing heat capacity values: qcs, Fe(s)cs, Cu(s)===mcsΔT0.450J/(g⋅∘C)0.385 J/(g⋅∘C)
