A 1.2 kgkg block of iron at 33 ∘C∘C is rapidly heated by a torch such that 12 kJkJ 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 (12 kJkJ ) was quickly transferred to a 890 gg pellet of copper at 22 ∘C∘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: qcs, Fe(s)cs, Cu(s)===

A 1.2 kgkg block of iron at 33 ∘C∘C is rapidly heated by a torch such that 12 kJkJ 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 (12 kJkJ ) was quickly transferred to a 890 gg pellet of copper at 22 ∘C∘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:
qcs, Fe(s)cs, Cu(s)===mcsΔT0.450 J/(g⋅∘C)0.385 J/(g⋅∘C)q=mcsΔTcs, Fe(s)=0.450 J/(g⋅∘C)cs, Cu(s)=0.385 J/(g⋅∘C)
Express the final temperatures of the iron and copper in ∘C∘C to two significant figures separated by a comma.
