Problem

Equal masses of liquid water (

c = 4.18\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}

) and solid iron (

c = 0.45\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}

) each absorb exactly

100\,\text{J}

of energy under identical conditions. Which statement is most consistent with this information? (a) The water sample experiences a larger temperature increase than the iron sample, because its specific heat is greater. (b) The iron sample experiences a larger temperature increase than the water sample. (c) Both samples experience the same temperature increase, since each absorbs the same amount of energy. (d) The temperature rise of the water sample is about nine times that of the iron sample, reflecting their specific–heat values of

4.18\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}

and

0.45\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}
