Problem

Equal masses of three solids each start at the same temperature and absorb 1.0 kJ of thermal energy. Their specific heats are listed below. • Aluminum: 900 J kg⁻¹ °C⁻¹ • Iron: 450 J kg⁻¹ °C⁻¹ • Lead: 130 J kg⁻¹ °C⁻¹ Which ranking correctly orders the materials by the magnitude of their temperature increase, from greatest to least? a)

\text{Aluminum} > \text{Iron} > \text{Lead}

\text{Lead} > \text{Aluminum} > \text{Iron}

\text{Lead} > \text{Iron} > \text{Aluminum}

\text{Iron} > \text{Aluminum} > \text{Lead}
