The specific heat capacities of three metals are given below
$\begin{matrix} Metal & Specific heat J \cdot g^{- 1} \cdot {{}^{\circ}C}^{- 1} \\ Fe & 0.470 \\ Pb & 0.130 \\ Zn & 0.388 \end{matrix}$
If 1.00 g of each metal is heated to 100° C and added to 10.0 g ofH2O at 25.0° C, what is the order of the temperatures of the final mixtures from the lowest to the highest?

Detailed Solution

specific heat: $Pb < Zn < 0.470$
It is the heat required to raise the temp. of one unit mass of substance by $1^{0} C$
More the specific heat, more amount of heat required to raise the temp.

order of temp of final mixture

$pb < Zn < Fe$
