AP Chemistry
6.4 Heat Capacity and Calorimetry
A student investigates the thermal properties of three solid metal samples: \(\text{Al(s)}\), \(\text{Fe(s)}\), and \(\text{Ag(s)}\). Each sample has a mass of \(10.0 \text{ g}\) and an initial temperature of \(25.0^\circ\text{C}\). The student transfers \(180 \text{ J}\) of heat to each sample. The specific heat capacities of the three metals are given in the table below.
Which of the following correctly ranks the metals in order of the magnitude of their temperature change (\(\Delta T\)), from greatest to least?
| Metal | Specific heat capacity (\(\text{J/(g}\cdot^\circ\text{C)}\)) |
|---|---|
| \(\text{Al(s)}\) | \(0.90\) |
| \(\text{Fe(s)}\) | \(0.45\) |
| \(\text{Ag(s)}\) | \(0.24\) |
Which of the following correctly ranks the metals in order of the magnitude of their temperature change (\(\Delta T\)), from greatest to least?
