Answer

Explanation:

Step1: Understand specific - heat concept

The lower the specific - heat value, the less heat energy is required to raise the temperature of a given mass of the substance. So, substances with lower specific - heat values will reach the target temperature faster.

Step2: Rank the metals

We rank the metals based on their specific - heat values from lowest to highest. The specific - heat values are: $Pb(s)=0.129\ J/g\cdot^{\circ}C$, $Sn(s) = 0.227\ J/g\cdot^{\circ}C$, $Cu(s)=0.385\ J/g\cdot^{\circ}C$, $Fe(s)=0.450\ J/g\cdot^{\circ}C$, $Al(s)=0.897\ J/g\cdot^{\circ}C$.

Answer:

Fe: 4 Al: 5 Cu: 3 Sn: 2 Pb: 1
